What do you exactly mean by "sharper". Is the cutting edge thinner? I haven't heard this before and I fully believe that it would cut way better if it were stiffer but to be honest I kind of doubt that it is sharper than a freshly sharpened, good quality knife. Because I witnessed a few times that these expensive Japanese kitchen knives cut through everything with very little pressure if you want it or not.

When you learn English but live in a household with non-native English speaking parents you learn a LOT less colloquialisms, idioms, slang and cultural references in English. It's not a bad thing, it's just a thing. Think of all the things you learn BECAUSE your parents learned English as adults. I've taught lots of English classes to adults and especially doctors and nurses focusing on Medical English terminology, verbal examination, bedside manner and phone calls. Lots of people would have LOVED to move to an English speaking country as a young adolescent like Dr. Mike so they could learn English before their mid 20s when some people can start in earnest because they have to focus on getting a degree. But yeah....the idioms of a new language are a lifelong knowledge gap but a lifetime of learning enjoyment. Just ask Victor Borge, Ismo or Yakov Smirnov... All comedians who turned the exploration of their second language into an art form.

Re panic attack in the grocery store: a lot of people think they’re having panic attacks but they’re actually experiencing sensory overload. People with sensory processing difficulties (often found in autism, ADHD, sensory processing disorder and sometimes PTSD) tend to really struggle in the grocery store because of the sheer amount of sensory input (the sound of music and announcements and beeping scanners, the other people, the lighting, the smells, the visual input of all the different products). Definitely something to consider if the grocery store is a struggle for you. Interestingly, I’ve had people tell me that propanolol prescribed for social anxiety also helps them cope better with sensory input.

2:50 right on! The mouth takes in water that is then pumped out through the gills. The gills filter oxygen out of the water as the water moves through them. The fun bit about sharks is they have two interesting breathing styles. One type is buccal pumping where they essentially just move their jaws to gulp water. Other sharks do ram ventilation, which allows them to breathe by swimming with their mouths open at all times. The water continuously passes through their gills this way.. but it means they can never stop moving.

I just about cried when he said “to you who’s lonely at home, I say hello.” I live alone and that meant so much.

7:35 reminds of when I got a bunch of blood tests to find the source of my chronic issues and I specifically asked them to look for Lyme antibodies. I waited a week as instructed and then had to call several times before they had my results and the recetionist told me that they were completely normal and there was nothing that could explain my symptoms. At my next appointment, my doctor was taken aback because the only thing they found was exactly what I had asked them to look for. Didn't really derail my treatment in any way, but I'm still annoyed that I had to go through another week of not knowing what was wrong with me because someone didn't read the results right.

The “fake fall” thing the meme was mentioning is referring to when your body feels like it’s falling because you fell asleep before you hit your bed so your brain never registers that you’ve stopped falling

2:21 that's something common if I'm taking a nap, when I think something that contains a shaking effect, I'll shake myself for no reason, probably the people near me are questioning why

"tired but wired" is so funny because I learned years ago (i am not a parent) that toddlers will get so tired they get like hyper + grumpy if you don't make them nap and now as an adult when I go a night or two without sleeping well and I get the same effect so I call it "toddler tired" when I'm so exhausted I can't get to sleep :')
