Personnally, as someone who grew up on a farm, I got little sympathy if I was sick, cows don't milk themselves. Strangely in 20 years working in an office I've had 3 days sickness (and I'm excluding accident related issues here), some people manage that in 20 weeks
Well you're either exceptionally lucky with your health or you're one of those annoying people who come into work with colds and stomach bugs and give them to everyone else. It really annoys me when people get smug about how little sick leave they've taken. Not everyone is fortunate enough to have great health.
