What happens when an ageing man begins to roller blade

Kids, don't try this at home. It is dangerous stuff and I have my aching body to prove it.

Yes, It was my introduction to roller blades. It was a mess. I was a mess. I was going in all directions and in none -- all at the same time.

I should remember my age.

People looking at me had signs of concern. I could feel in their eyes a cautious and pitiful look.
