I don't like to be preachy - people in glass houses an' all that - but every now and then it can't hurt to give out a little reminder.
Natalie's husband has just reached a milestone, having made 100 blood donations. I've got a long way to go before I catch up.
I was about 30 when I started giving blood. I should have started earlier, but it was always one of those things that I just never got around to even though I knew I should. You know - procrastination rears its ugly head yet again. But now I go regularly. The nurses there are always lovely, they're pretty adept at finding my sometimes-reticent veins and I leave feeling that even I do nothing else, at least I've made one tangible contribution to the community that I know will be valued somewhere down the line.
Australians can check their eligibility to donate blood and make appointments with the Australian Red Cross Blood Service here: http://www.donateblood.com.au
