Peyton Manning has quite a bit on his plate at the moment. Between getting doctors to clear him medically and trying to get Jim Irsay to clear him to play for the Colts, Manning is playing all sorts of games in the media.

Not only could it be unsafe for him to resume play in the ultra-violent NFL, but unlike many other stars in the league, Manning has numerous options outside of football that he could pursue.
None of them involve taking hits from NFL players.
