Another AIBU has got me thinking...
(this is not a dig at any other posters, honestly, it just literally made me think)
What stops you, if you don't donate blood or haven't signed the donor organ register? Do you have worries or concerns about where the blood / organs may be going, do you feel ill at ease with medical procedures, or other reasons?
'Cos I really think that if at all possible, we should all do it. Really. Unless IABU!
If you do donate / have signed, what really really motivated you to 'just do it' (aargh!) in the first place?
