From the videos I've seen, he just does trial and error - no math or understanding involved. That's not engineering - that's called design. Didn't stop him from bashing engineers in one of his videos saying that school was pointless. After that, I stopped watching his videos. Thankfully I only wasted time on 2-3 of them, including the swearing roomba.
Meanwhile I highly doubt he knows (or knew) anything about fatigue, trusses, or kinematics, things you have to have an understanding of in mechanical engineering. Maybe he learned after the fact, but I don't really care.
As a mechanical engineer: if a software engineer completed school, they're an engineer, deal with it. We're not talking about someone that doesn't know what they're doing cobbing things together for 1-off demos like Michael Reeves
1: Believe it or not, face moisturizer really helps. You don't need anything particularly fancy, I just use the Gold Bond brand stuff from the grocery store.
When your skin gets dried out it starts to overproduce oil to stop the dryness. But this overproduction of oil contributes to acne. Moisturizer prevents it from the start.
2: As others have said, regularly washing your pillowcase helps as well, as it prevents oils and bacteria from building up. Wash it weekly at minimum. Having multiple pillowcases to swap in and out will help as well. And if you shower in the mornings, washing your face before bed every night will also cut down on oil accumulation throughout the week.
3: When you get out of the shower, use a separate towel for your head. Some acne is caused by microbes being transferred from different parts of your body. A bacteria that's benign in your armpit might cause issues if it gets moved to your face.
4: As others have mentioned, an exfoliating facewash during showers also helps.
5: I don't buy acne wipes anymore because they're overpriced. When I can tell some form of blemish is forming, I put some isopropyl (rubbing) alcohol on a q-tip and rub it on the spot for 30s. And yes, I count the full 30s. This part's probably easier for me since I was finished with puberty almost 15 years ago, so it's easier to treat the occasional zit.
Eh... It depends. People can enjoy a thing while also recognizing that they wouldn't want to emulate it. Not always, but it should be handled on a case-by-case basis
