I guess im getting old

My standard line is "I may be getting older but I refuse to grow up" Well, riding bikes & other motorized stuff makes me think perhaps I am growing up... As GTX John mentioned, the ground seems so much harder than I remembered... I'm 63 now & I'll still ride a wheelie, do burnouts & generally act the fool cause I still find it fun but I tend to apply a little more caution than I ever would have in my 20's 30's or even 40's... Funny thing is how many 20 & 30 year olds today grew up so sheltered they've never done a wheelie or even a nice big smoky burnout...
