I'm around 60 (going by your earth years) and I still look and feel around 25-35 of your earth years. No dicky knees, no back aches, no crows feet, no double chins, no pot belly, etc etc. I do have literally a few gray hairs popping thru, but they've been around on me for over 30 of your earth years.
There's something about the aging process I wish to discuss. I've noticed (apart from me) some people can look 50 or 60 when they're around 20-30, and when they're 50 or 60 they STILL look the same. Eg, William Burroughs or Keith Richards.
There are different stages of 'I feel old' when it comes to watching footy. When I got my first footy stickers and album from the newsagent Dale Weightman was still playing and he was born in the 50s. Most of our flag sides in 92/94 were guys born in the 60s.
In the 2001 draft, people from my year 12 school year (though not my school) were getting drafted which was kind of a weird novelty. The following year they were playing. By 2007/08 it was 90s babies being drafted which as an 80s baby was weird. Now players from 2000 are being drafted. This year players who were born the year I was eligible for the draft will be getting drafted. I'll be in my chair listening to talkback radio...
