Did a bag sketch envisioning some Marvel mainstays aging in real time.
Steve would be fit, but still look oldish…a compromise due to Super Soldier serum.
Figured Tony got the extremis nanites to freeze his aging in his mid 50s.
Imagined Bruce just got old, but maybe his Hulk physique sorta regenerated him when he’d have a heart problem or something.
As for Peter & Felicia? Old and retired. Living in Soho? Maybe they run a photo/art studio w a cafe in it?
