It's shocking to me the number of people I've come across who've no idea how to cook or find it to be too troublesome to do. Moreover, feeding yourself should be the single most primal skill for anyone to have.
I realize there's a lot to unpack here. Some people are taught / learn to cook at a young age while some people have parents who've never cooked for themselves. Personal preference, finances, and scheduling play a huge part. The definitions of "cooking" and "feeding yourself" can vary widely. So, I'm not claiming everyone should know how to make a roast chicken dinner for four with sides and dessert. Although, I do think people should be at a level above boxed mac and cheese and microwaved air-fried chicken nuggets.
Cooking is, in my opinion, shopping for fresh foods and turning them into a meal. It's about your health, your pleasure, and your finances.
When my best friend first moved in with me I had to teach her how to cook lol. When I was a teen my mom forced my brothers and me to cook dinner a few times a week which I'm really thankful for
