A lifetime of watching sports:
10: Maybe one day I'll be able to do that
20: I betcha I could do that
30: Sure not the crazy stuff, but I could totally do the basics
40: I sure can't do that anymore
50: Who am I kidding, I could never have done that
60: Sure they're good, but not compared to the ones in my day
70: They're superhuman these days, we were never doing stuff like that
