Yes, I just used google's new opinion search feature. f***ing idiot...
I think it is a cool idea. I donate blood regularly, but I know a lot of people who would probably also do so if they were getting paid.
Last year a bunch of my friends who never donate blood went to Pharmovs on the UFS campus, because they were paying R150 for blood to be used in trials. There were queues of people. This means the problem isn't that people are scared of the needle or shit, but just need some motivation.
I think this has been successful in Scandinavia and in other countries, where people are paid for blood. Its a good incentive.
