Shame? Dang, the best years in my life each felt like a century compared to now, and they were so sh***y they'd make these kid today evaporate quicker than flatulence in a convection oven tossed into a torando - yet they were awesome too.
It is counter intuitive tho. Hell, I could skip through getting a doctorate now, if my memory didn't fall to hell. I remember long deep summer evenings as a kid. Just doesn't seem the same now.
