Diver Safety - Donating blood

Here's an interesting one from the DAN website. We had a recent diver that donated blood in Baucau then went diving on the way back to Dili

Q: If I donate a pint of blood how soon afterward is it safe to dive?

A: Immediately following blood donation, the volume of circulating blood is reduced. Provided the donor eats and drinks normally, blood volume returns to normal within 24 hours. Diving within the first few hours after donating blood is not advisable because of the possibility that reduced blood flow could cause impaired inert gas washout after a dive, and thus an increased risk of decompression sickness. We have no reason to believe that it is necessary to wait more than 24 hours after donation before scuba diving.

Wow, didn't expect an answer to that question...! And concerning the answer in combination with East-Timor; giving blood is good and diving is fun! Decide for yourself...
