Because Arnold is only 18 in that pic and the other playa just said he was 22. If you wanna go there with comparisons, then here's Arnold at 22...hell, I'll go with Arnold at just 20.
BS, what's with the jealous crap?
He looks as good at 22 as Arnold did with 18.
So what? he'll never reach Arnold's levels, but i would guess he doesn't want to.
This comparison does not downgrade Arnold in any form.
