THE best Christmas present your readers can give is the gift of life. I am writing to encourage them to become blood donors.

Traditionally at this time of year blood stocks can drop by up to 10 per cent. This and the rise in the incidence of winter infections like colds and flu meaning fewer people can donate, has prompted the National Blood Service to launch an urgent appeal. To find your nearest blood donor centre call the National Donor Helpline on 0845 7 711 711 or visit www.blood.co.uk
