I'm not as young as I once was

Why do hangovers hurt so much more as I get older. I drink higher quality beer, wine and spirits now so, in theory, that should help the hangover situation. Nope. It doesn't. I used to drink the cheapest shit I could find and NEVER got hangovers. Maybe I should go back to that. HAHA Yeah right! That stuff would kill me now! Still had fun though. Will probably do it again this weekend with my rugby buddies. Long live Excedrin and McDonald's!!! They will cure what ails you! :)
