So far today I have:
- Taken Ethan to be groomed (they shaved great gobs of hair from him; he looks like a naked mole-rat now).
- Inspired by Ethan, gone to get my own hair cut at Ray’s Place. I do not look like a mole-rat. At least not completely.
- Donated plasma at Canadian Blood Services.
- Ordered a new pair of Brax trousers from Dow’s, something that’s been on my to-do list for ages.
I’m always asking questions of the friendly and helpful nurses at Canadian Blood Services, and here’s what I learned today:
- My hematocrit reading was 42%, which means that 42% of my blood is red blood cells; this means, give-or-take, that 58% of my blood volume is plasma for the taking.
- Each plasma donation involves extracting 500 ml out of me.
- The average person has 5 litres of blood (I learned this from Wikipedia)
If my math is right, that means that roughly, 2900 ml of my blood (58% of 5 litres) is plasma, and that I donated only 17% of that to the cause, leaving me with 2400 ml still sloshing around inside me to do whatever it is that plasma does.
It’s only 3:35 p.m.–I have high hopes for the remainder of the day.
