Your future doctor is using ChatGPT to pass medical school, so you better start riding a bike and eating healthy now.
@duanegran eating healthy and riding bike for everything shorter than 5km might be a wise decision anyway, totally independend from your future doctors education.
@Reinald @duanegran why for shorter than 5 km? I tend to choose riding my bike over walking the longer the trip. If I'm just gonna go to the corner store a block away, I walk.

@Shanmonster @duanegran different people have different needs. For most people about 5km is the threshold between "quick and easy ride" and "effort and sweating involved, and time invest".

If you like to walk - go ahead. If you like to ride longer than 5km - feel free. But please don't assume your preferences would be good for everybody.

@Reinald @duanegran I did not assume that. There is a significant problem with bike theft where I live, so I tend to use my bike for the trips which are too long for me to walk, that's all.
@Reinald @duanegran FWIW, when I was going to college, my choices for getting there were a 2-hour bus ride or a 50-minute bike ride.
