Curious facts about blood

My latest blood donor magazine has some doozies:

* Claret-coloured blood suggests haemoglobin may be leaking from the red cells, a natural process of aging. (So you get less blue-blooded with age?)

* If you had a fatty meal the night before your blood might be pinkish - probably not good if you're trying to impress the nurse!

* Some oral contraceptives turn your plasma bright green (no they don't say which ones), while self-tanning pills can make it flourescent orange.

So does this mean you glow in the dark?
