Bloody thursday

I donated blood today, so I'll be taking it slow with the breath-holding for a few days at least. They of course measured my haemoglobin, which I've been curious about for some time but too lazy to get tested. I got 174, which is pretty good I guess. It should still be safe to get it up a bit, but I guess over 200 is considered too high, at least for an average person.

The donation (450ml), I was told, will cost some 10g of haemoglobin, but that's not too bad. I'll get it back soon enough...Anyway, it's a small price to pay for someone's life...
