I visit family in other states and I get comments like “I can’t believe you are so thin.” For context I am a healthy weight and I eat what I consider a reasonable diet. I sit and smile while I watch them drink soda and eat pure sugar and salt. I don’t care about your life choices but don’t act surprised by someone that’s a normal weight.
Are you sure it is not the other way around? Maybe the driven people who are physically fit are moving to higher elevation. If someone is obese they probably aren’t going to move to rual mountains
