I don;t either, and I think it’s partly because I almost feel a little selfish as I am diabetic. Although thinking that is in itself, selfish, as it’s ignoring the thousands of others that would benefit from the money! Would definitely encourage others to donate though, and am considering some form of sponsored bike ride/race in the distant future possibly…
I find charities in general a troublesome proposition, I’ve heard too many stories of silly wastage of funds and misplaced ‘help’… Means I feel I have to do lots of research before picking a charity!
