You know how, in order to donate blood hor, I think you can't
sick during that 2 month period or something leh.
And I think our local people have much more things to do rather
than to waste time and donate blood.
I suggest those major companies offer help to Singapore Blood Bank,
say sponsoring vouchers. Say from this period to next week, you'll
get $5 McDonald voucher. 
You know, Singaporean loves incentives. 
But I really feel that this is not the way to do it. It's more like
selling blood for vouchers instead of volunteering donating. But do
you'all have a better solutions?
