I used to be able to (but not now) climb a lamp post and sit on the top (came in very useful once in Blackpool!) - did my training for that as a little'un, challenging my brothers mates to race to the top of the rugby posts down in the school field near our home!!!!!
After crashing my bike a decade or so ago, leaving me unable to walk more than a couple of yards and being told I'd end up in a wheelchair - I can now walk about 3 miles without needing to sit down!!!!
