I lead a pretty healthy lifestyle, I think. I eat plenty of fruit and veg and cook from scratch virtually every day, drink plenty of water, exercise and generally get enough sleep. I do suffer from depression but not currently. I'm now fighting my third bug in about 6 weeks and I'm sick to death of feeling crappy.
If you're one of those lucky people who are rarely ill, please share your tips and suggestions- I'm so sick of being full of snot!
