judderman – really sorry to hear that.
I'm 45 this year. When I was in my early 20's all I really did was get p*ssed and ride bikes (engine and pedal-powered).
Now I'm in my mid-40's I'm happily married, got two lovely daughters, plenty of good mates, nice house, car, motorbike, cellar full of expensive bicycles, good job, enough cash to be comfortable – all good.
But ultimately I still like to get p*ssed and ride bikes (not simultaneously!).
Some things never change, and I have no intention of changing anything. If I want to do something I will, thinking if it's appropriate for my age never enters the equation. (Though I won't wear Converse All Stars any more, or drainpipe jeans, as I suspect I might look a tad desperate).
