Continuous glucose monitoring

Last week I wrote that I scored a 5.7 on the HbA1c test during my annual checkup. That number is just into the range of pre-diabetic, which is rather alarming. With no other levers to pull - my sleep and exercise regiment is on point, the only lifestyle choice I am making is to limit carbohydrates. More so than I’ve already been doing for over a decade. It’s kind of difficult to cut carbs when I hardly eat any sugary products to begin with. I would be cutting into the staple carbs I eat with meals: rice, bread, noodles, fruits, et cetera.

Ideally, I want to be able to see which of those carbs are spiking my blood glucose level. It’s not prudent to cut out carbs completely, because I need some of it for sustenance, especially after workouts. Therefore it would be helpful to see if white rice spikes blood glucose, but a slices of wheat bread does not (or vice versa, I don’t really care). I will then only eat the carbs that do not elevate blood glucose.

Turns out there are devices called continuous glucose monitors (CGM). Exactly as the name suggests, it constantly measures a person’s blood glucose level (every five minutes). An app on a smartphone collates the data, and users can see in real time if it’s normal, elevated, or too low. Originally developed for type one diabetics - they need to check their blood glucose constantly, CGM devices are now broadly used by people (diabetic or otherwise) wanting a clear picture of their glucose profile.

I asked my doctor to prescribe one to me, and she agreed. But there’s a problem: because I am not a type one diabetic - or any form of diabetic, Kaiser Permanente insurance does not cover the CGM. I will have to pay out of pocket (in the American healthcare system, there is no money in prevention). The primary cost driver are the patches that sticks to the skin (for measuring). Those need to be replaced every 10 - 14 days (depending on the brand).

It’s a necessary expense. I need to see if my blood glucose level is indeed higher than what is considered normal. No better method than measuring (kind of) at the source. Sometimes HbA1c results can skew higher by other factors, so I want to check if that 5.7 might be a false positive (if you will). More to come!

It's nap time

You know things are slow at work when a coworker falls sleep while watching a YouTube video. Granted, the snoozing is probably not due to boredom. Rather it’s likely insufficient sleep. Sure we tend to yawn when we’re bored, but then we’d go find something to un-bore ourselves. Nobody goes, “You know what, I am bored. Let me go take a nap!”

Indeed, the workday does go by quicker when there is more stuff to do. This workload ebb and flow comes with the territory of one, working at a university, and two, being on the service side. People call us when shit goes bad, so if we’re busy all the time, then something is horribly wrong. We are smack dab in the middle of the Fall semester, so not a lot of things are going wrong at the moment (knock on wood).

The weather in San Francisco has finally turned cooler, a real autumnal feeling. That coziness probably adds to the drowsiness factor (I definitely sleep better during the winter months). The coworker did just return from a heavy lunch, too, so all the pressures of wanting-to-take-a-nap were working against him staying awake. Sadly, a public university is not the Google campus: there aren’t any nap pods around here.

As a purveyor of consistent, quality sleep, you won’t find me doing the head-nod into slumber whilst doing a sedentary activity. I haven’t done something like that since my college days of falling asleep in class. For obvious reasons, my sleep schedule was all over the place back then. No, professor, your lecture isn’t boring! I’m simply running on fumes.

These days, I no longer sacrifice sleep to the altar of continue playing a video game, or keep watching a TV series. I purposely leave social gatherings early in order to preserve the amount of sleep I get. It is too important for brain health to forsake.

Sugar how you get so high

Yesterday was the first time in my life I got the flu vaccine. And let me tell you, I am feeling like crap today. Make sense, right? The vaccine is effectively introducing a small strain of the influenza into my body. Of course it is going to react as if I actually got flu. At least the symptoms aren’t truly on the levels of a real one. The last time I got it - more than a decade ago - I was bed-ridden for two days.

It was a smart decision to not get the latest COVID vaccine at the same time. Despite what the Travis Kelce commercial says, asking your body to fight two invading viruses concurrently might not be the best idea. My coworker got both the flu and COVID vaccine at the same time, and he was down in the energy dumps for two days. I’ve a history of symptomatic reaction to the COVID vaccine (the second Pfizer shot was killer), so I am delaying what would be the fifth shot to a later date.

I also got the annual blood test yesterday: the usual cholesterol and glucose measurements. Turns out I am pre-diabetic? My HbA1c is 5.7, which is barely into the pre-diabetic range. I am kind of dumbfounded at this. I’m rather religious with proper diet, sleep, and exercise - and have been since my early 20s. I don’t drink or smoke, and I avoid added sugar whenever possible. My weight is completely normal for my height. How the French am I pre-diabetic?

Since I already get eight hours of sleep per night consistently, and exercise multiple times per week, any adjustments to be made will not be in those two areas. It will have to be diet. Moving forward I will cut back on carbs as much as possible, and eat more vegetables and fibrous foods. Let’s check back in six months when I get the next blood test.

It's up to me now

My dad is scheduled to retire after the end of this year. A well-deserved long rest after over four decades of toil. And I do mean toil: working in construction back in China, and then laboring in a warehouse here in the States, before ending up back in construction. It was non-stop, with scant vacations. Dad’s ceaseless work sustained our family through some tough monetary times. My current life would not be possible without his dedication to the family.

Now that he is retiring, it is time for me to return the favor. That’s the rule in Chinese culture: you must be filial to the parents. After my dad stops working, his only income will be from Social Security. There isn’t a grand retirement account to draw money from. Remember: our family was near the poverty line for a long time. Back then, the money coming in went straight to supporting a family of four. It was always going to be relying solely on Social Security after retirement - for dad and my mom.

Obviously, the monthly Social Security check is going to be far less than the paycheck my dad is getting from his job. That means the current lifestyle supported by that salary will either need supplementation, or hugely adjusted down. The day-to-day fixed costs - such as food and rent - can be covered by the Social Security check. Where I come in to supplement is during outings and special occasions. It’s up to me to pay for the that restaurant bill. Same with plane tickets and accommodations when traveling as a family. Need a new vacuum cleaner? That’s going to be me as well.

Good news: I have a brother to split the load! My parents sure are smart to have two offsprings to support them in their latter decades. Half-joking aside, I dutifully relish the opportunity to give back to my parents. It’s the least I can do, a just reward for a life sacrificed for the kids.

Don't heat it up

October in San Francisco has brought along the typical few days of hot weather (hot for this region, anyways), even though it’s autumn. This brings a unique problem to someone like me who lives in a studio (read: very small). When the temperature is high, I cannot cook at night. The room (singular!) is warm enough already; cooking a hot meal adds heat to it, delaying the natural night cool down. The slower the room cools down, the more difficult it is to fall asleep.

A cascade of negative consequences, that’s what it is. Good news is, I live right by a mall with plenty of food options. So on the hot days these past few weeks, take-out dinner was the only sensible option. Not that I need any extra excuse to not cook. The downside of course is the hit to the wallet. Inflation is still high, food prices are still ridiculous. Can you even eat a non-fast food meal for less than $20 these days?

In addition to not cooking when the weather is hot, I also do not use my LG OLED TV. Did you know that OLED televisions consume more power than the equivalent LED unit? All that wattage has to go somewhere: radiating right into the room. So what do I do for entertainment on a hot October San Francisco evening? I use the iPad. That thing runs so cooly that it doesn’t even have an internal fan. Indeed it’s kind of slumming it to go from a 65-inch screen to a 10-inch screen, but I must avoid heating up the room unnecessarily.

Because as mentioned: sleep is utmost importance. The body needs to cool down 1 to 2 degrees in order for the person to fall asleep. The warmer the room, the more challenging it is to get there. What would be ace is one of those mattress toppers that has active cooling. If climate change gets worse, and San Francisco sees more and more hot weather days, it’s something worth considering.

You can go to Chinatown for a meal under $20.

Up and up

Word on the street is that Netflix is once again raising its prices. For 4K top quality Netflix, folks are now looking at $22.99 per month. Is it just me or is that dangerously close to basic cable pricing? Include the other streaming services a person is likely to also subscribe to, then it is basic cable TV costs. We’ve cut the cord, but the money is still flowing out.

Fortunate for me, I don’t subscribe to Netflix. But I am not delusional to think that other streaming services - the ones I do subscribe to - won’t hike their monthly fees soon enough. Imitation is the sincerest form of making money. Remember a few months back when Netflix effectively banned password-sharing? It seems to be a surprise revenue increaser for the company. So of course Disney Plus has begun doing the same thing. Our neighbors up north in Canada will receive the initial brunt of the crackdown. It’s just a matter of time for us here in the States.

My friends who are sharing my account (would this be incriminating?) will have to find other ways to watch Disney programming. Legal or otherwise.

Prices for everything keep going up and up, way too rapidly. A good way to combat this, at least for McDonalds, is to use its app. The deals offered on the McDonalds app really blunts the hefty prices. Yesterday there was a buy-one-get-one-free deal on the double cheeseburger. Two sandwiches for less than five dollars is a win these days. Also, the more you use the app, the more points you earn towards free food.

Not to say you should make McDonalds a constant staple of your diet…

Right from the table

I am a big fan of the restaurants that do ordering right at the table using QR code. I think it is a great system, kind of a step up from fast food counter ordering. Everybody’s got a smartphone these days, right? A quick scan, order what you want, and the food arrives to the table in short order. Best of all, it allows folks to easily pay for their own meal (bonus if I can use Apple Pay right on the website). The QR code system negates the need for card splitting, or heavy Venmo calculations. Everybody gets to earn credit card points!

It’s awesome for large groups. Especially when said group is a bunch of car enthusiasts gathering once a year, most of us having previously only met on the Internet. Surely a restaurant would hate to split a bill amongst ten credit cards. Having one person pay, and then accept Venmo from everyone else, is a huge hassle as well. That’s why I was surprised and relieved to see the restaurant was the order-from-the-table-via-QR-code type.

Ordering from the table has got to be a thing borne out of the pandemic, right? Back when indoor person-to-person contact is to be avoided as much as possible. Instead of a server coming around to take orders, let people order for themselves digitally. The point-of-sale is packaged right in, too - that’s another interaction eliminated. The only face-to-face potential is when the server brings the food. But even that, I’ve seen in some restaurants, can be done by robots.

This is one of those necessary changes spurned on by the unfortunate pandemic that we are happy to see continue on. Another one is the hybrid university classroom, where students have the option of attending in person, or joining virtually from Zoom.
