I turned 40 last december,turn 41 this december, if you want to think about it in a bad way you could get real down, Me I felt pretty bad to start, luckly my mate at work, Brian, turned 60 a few months later,
Now we will be up brickhill tomorrow and i will still be behind him all the way up and all the way down, we both do 70 miles a week to work and back, both on cannondale badboys, mine single, he's geared, sunday i will be on my cotic, he will be on his rocky mountain, i will be huffing and puffing and so will he, but in 20yrs if i'm riding like he does in the morning, i wont ever have a worry in the world, age doesn't matter a toss, just live and don't count and be as young as you want..
I like to look at it like this, i feel like i'm twenty but i have a beautiful wife, two beautiful daughters, my own house, 2 cars on the driveway and garage full of bikes, health and money in the bank,
20 or 40 ?, im happier now than i've ever been, i'm glad im 40..good luck and enjoy the wisdom of life
