absolutely, cousin aged 21 didn't do anything about an anomoly down stairs, 12 months later he has 8 secondary cancers, primary being testicular, started chemo TODAY!!
friend has had his foot amputated just above the ankle, IED in afgahn, although is in mighty fine spirits with a 'hey, i'm not dead and i've only lost a foot, look at the bloke next to me in here (sellyoke) with 1 arm and no sight' attitude
certainly puts things into perspective
