why flea never wearing a shirt on RHCP clips?

I guess that it is for the same reason I don't use much shirts... But, for him, it's is clothes at all (because, in a lot of gigs he's naked..xD) We feel freedom, you know? Like "if everyone else is doin' somethin', lets not do that", you feel like your are alive, feeling the wind in your body and stuff like that. But, it's is for me. Maybe flea just likes to show his abs... Eveyone have a different reason, i guess.

i think flea wants to feel free about when they perform on the stage,it makes he feel like hes only on his normal way of living
