Same sort of thing, happiest I've been "working" was helping a mate with some labouring of a weekend back when I was 17. It's amazing the satisfaction you get at the end of the day feeling 100% exhausted, but with several tonnes of concrete mixed, or a few thousand bricks moved (even seemingly arbitrarily from one spot to another).

Not something you really want to be doing for 30+ years though, but to be fair, I'm not sure the prospect of staring at this screen for 30+ is especially appealing either...
