Construction, Darren is tough work. I love the feeling of being a little sore at the end of a 10 hour day after picking up 16mm x 3m x 1200mm fire rated plasterboard sheets all day and screwing them on to hardened steel studs. Being able to do one thing all day is not necessarily going to mean you can do something diametrically opposed to that for another 8 hours without suffering in some small way. Ya just soft mate, all those years sitting on a bike and having to talk to naughty people.
