Donate Blood Readers

Loads of Colleges encourage blood donation.

My personal experience started with a very good lecture.
The guy who gave it, explained to us that blood is very precious and that the human body is its only manufacturer. So in the times of need for a fellow human, the only way he can be saved is by another persons blood. And the fact that we have a buffer stock of blood in our body(about 200ml per kilogram of body weight). So its expected of healthy people to give their excesses(which are hardly of any use to them anyway). At the end of the lecture I was like 'Why shouldn't I give blood?, rather than whether I should give blood'.
In a way the lecture was very similar another one that I had in my 7th. That one flashed in front of my eyes. Then it was about the use of firecrackers. Now I loved bursting firecrackers. And doing some things with them that may be I shouldn't have been doing. But I always looked forward to Diwali for getting another chance to experiment with them. The lecturer explained to us that not only do firecrackers harm the environment causing noise and atmospheric pollution, they are also usually made by employing child labour. So it would be a better society if people restrained their flamboyance. It was a very effective lecture as I stopped cracking crackers (though I have cracked a few on others insistence). And I try to encourage people to the same.
My blood donation itself went very smoothly. We went to give blood with our group of friends. The blood bank had set a limit of 45 kgs and I was measured at 49. I had no side effects after they had extracted 350ml of fluid from my body. Then we spent three quarters of an hour for refreshments roaming around bunking lectures. We would get the attendance of course.
I try to tell people to give their blood too.

And I will do the same at every opportunity(twice a year until I graduate). And that says it all.
