for those who're scared of needles or the process of donating blood (or are maybe just reluctant to take a trip down to HSA)...
it's understandable since so many ppl have phobias of some kind (and everyone is busy).
nevertheless blood can only be kept for a limited duration (42 days or so) so a constant supply of readily available blood is needed all e time.
you might also be interested to know that a single pack of whole blood is usually split into a few usable products:
red cell concentrates (for the 'normal' blood transfusions);
platelets; and
fresh frozen plasma or cryoprecipitate (helps with ppl with blood clotting problems).
possibly other products which i can't really think of right now.
in short, a single donation might help up to maybe 3 ppl?
so if u're healthy, not a hep b carrier or have other medical issues, do think about donating if u can.
(you can always just look away from the area they're inserting the needle into.
