My last time was last month. I was trying to show my son and his mates what a 'manual' was.
I borrowed one of the kids BMX to demo………never been on a BMX before….
Anyway ended up falling off the back or it in a heap on the floor – they laughed and I cried ;)
I'm just off to the hospital now to have an operation on the prolapsed disc I caused, exactly 2 years since the the last operation caused by a similar exploit :(
One day I might learn, but until then….
