Oh oh.....just when I thought this thread was managing to stay away from the infamous helmet debate LOLBack to helmets - I have recently been put onto rat poison (Warfarin) for a couple of months due to DVT after a long flight and the medics insisted that I started wearing a helmet. Apparently head injuries are especially dangerous when you are on anticoagulants. In about 60 years cycling I have had my share of falls and damage but never anything that a helmet would have saved. However I have got used to it quite easily and now feel unsafe without one. Strange really.
