I found out what my blood group is by donating blood.
My older sister convinced me to start donating blood, now i do it every six weeks (provided I’m healthy).
VEry few people realise how easy it is to donate blood and that it’s relatively painless. It’s also a proven fact that it’s healthy to donate blood, and it saves lives.
Giving your blood to people who need it is of no cost to you, and it doesn’t harm you in any way – if your healthy and would like to help others but don’t have much time to spare, donating blood is an hour every 6weeks and can thus be your charity for life. And you feel really good afterwards.
