In tradition of the ol' ADB's..feel free to add your own truths
You know you're getting old when...
even with spectacles you still need a good magnifying glass and a bright sunny day to read the numbers on main jets!
when you build your bike box stock standard and you're justifiably proud of the fact!
when simply putting on your safety gear instigates the need for a short pause to catch your breath!
when gravity appears to be on the increase!
