that's what your legs are for ;)
no but seriously, i can't remember who it was now, but someone was shown in one of the tattoo age videos (i think, maybe it was another video??), an artist who i like and respect, who had a lot of space left on his legs, and i thought "aha! that's smart! and sneaky!" but understandable. hell, i want to get tattooed still when i'm in my 50's! and im curious to see what i will be getting tattooed when i'm that age.
