The impression someone gives in public is based on a lot more than height, and although autism does factor in its not usually a physical danger. Body language and facial expressions are more important, you can tell if someone’s stressed, or in a rush, or calm. There was a guy who was crazy tall at my last job, like nearly 7 feet tall, but he was always very polite and made funny jokes, and not once did I feel afraid of him.

Sort of hard to reconcile how similar humans are to each other while exclaiming we are all snowflakes too.

Spending 30 years doing the same thing doesnt mean they weren’t happy. Thats quite an assumption to make.

It really depends on the person and the drug. People can and do quit cigarettes cold turkey and succeed relatively often. Harder drugs like benzos or opiates have a much smaller percentage who do that, and even then most dont do it by choice.
