I used to deliver to a few 'benefits street' roads. They all had ok cars, dressed nicely, etc. My 'stuff' might be a little bit nicer than theirs, but they didn't have to waste their days going to work.
I could pay for an Ironman or any other race I fancied... but something else would have to give. Did a 4* ski holiday earlier in the year... cost me a mid summer holiday.
As I'm a postman, most of us are fairly fit, at least at a basic level- you have to be, to walk 3-4 hours every day. There's one guy who runs a bit, probably doing a 50 minute 10K. Another guy who's getting on a bit, but did a 3:35 marathon many moons ago.
I would say I'm the fittest, or close to it. I'm also one of the fattest too though. I like the strawberry & cream one
