I think you need to consider if you're mentally prepared, if you're physically ready, what exercises do you enjoy, and what your goals are.
The answer would be anecdotal.
I would say the elderly because as we know they lived longer then us and have experienced much more then we have, when you look at it from there you would see why they are more respected. On the other hand foster teens are not treated as good is because majority of teens that come from foster care don’t have a high school diploma and struggle on relationships so they are thought of as a burden.
