"For what it's worth, I think anyone can reach 2000, and likely 2200, with serious study and play. It does require a lot of work."
Chuddog, would you place an age barrier on this? Do you think someone in their 60's (early or mid 60's can still hit 2000, or even 2200)?
I'm in my mid 50's.
2000 FIDE would have to be good as the brave Garry Kasparov refused to play anyone over 2000 in his simuls.
There you go.
