Bernard O'Shea: Five things I wish I’d known in my 30s (but only learned in my 40s)

Bernard O'Shea: "Scientifically, it turns out your 40s genuinely are a turning point. Your muscle mass naturally starts dipping every year after 30 unless you 'maintain a strength-training routine'. A routine! I’m lucky if I manage to bring the bins out without needing a three-minute bsit-down on the wall."

1. Your body isn’t a temple — it’s a community hall
