But just like I can, and occasionally do, enjoy social interactions but usually prefer solitude, while I can, and do often, greatly enjoy food there are still plenty of time when hunger is just an annoying disruption.
All of the stuff that you have built up around food can exist just fine separate from it. You connecting socialising and bonding with food is just habit. That's fine, but it isn't universal.
I generally don't like food. Sometimes I crave something specific, or want to eat at a nice place. But 6 out of 7 days out of the week, food just isn't appealing to me, and is a chore to eat. It's basically like flossing.
Ever since a time when I was a teen and had to fast because of an esophagus problem, I haven't really felt hunger the same way. It's possible for me to go a few days without eating and not notice it or feel hungry. I can tell when I'm very hungry because I get lightheaded and weak around day 3. (Note, I don't do this intentionally and it isn't often I go days without eating).
So Soylent (or equivalent) is really helpful in making sure I get some food everyday.
I mean, I agree with you and everything but you're saying "this thing is so important to me I cannot understand other people". There are a reasonably large number of people who would be very happy if they only ever ate a bowl of cereal and a banana for breakfast every single day for the rest of their life. I don't understand it, and I wouldn't like it, but I don't want to prevent them the comfort they get from that.
Who does exactly?
Food, to me, represents more than replenishment of nutrition. It represents meeting and understanding my coworkers. Learning more about my significant other or unwinding with this person to talk about our week. Even when it's not a social situation, for me it's a treat. I completed some work and now I should treat myself by revitalizing my body with a substance that tastes good. It's a great motivator.
It's such a fundamental part of being a human being I can't at all relate to seeing it as a mechanical process such as flossing. I can't think of a worse comparison: when you're flossing, you're alone, and if anything anti social. Eating couldn't be any more be the opposite. It's something that all humans can relate to and bond over no matter what your opinions are.
Flossing isn't a part of our culture. Food is a part of every culture.
