How does it feel...?

Today we had blood donation camp here in nVidia. So a mail was circulated informing about the same. In the FAQs attached with the mail, there was one question:

How will I feel after I donate blood?

And in the the answer was:

Most people "generally" feel "great" after giving blood. And blah blah.

Now that was a typical Puneri answer I suppose. :D

BTW, I donated blood for the first time today and I do feel "great" after doing so... ;)
