To me it would be the opposite; we all have our faults, so how do they manage the feats that they do?
There's no point idolizing people for their accomplishments in the "they must be perfect" kind of way.
Ie I look at John and see someone amazingly fit for their age (very close to mine - only a few years older, yet he appears younger); I'd like to learn more about his routines (running and judo?) to see how I might benefit from the same.
I’m curious too, in the Lex Friedman podcast/interview, John described he oftens “runs on” a diet of pizza and Diet Coke.
The common stereotype is "heroes are narcissitic and have skeletons in the closet", but there are valid reasons for an otherwise good person to fail in what may be common sense to others.
