Koi to Kenketsu - Ch. 1

[xanon]

What? No vampire? No blood drinking?

Seriously though, donate blood if you're able to!

 

[BCS]

I'm B so all my blood would just go to pharmaceutical companies anyways

 

[kingalthur]

in my country, the standard is 350mL
but sometimes they can took more than that
also I'm B+ and I used to donate my blood regularly since I was in high school, tho I have less often to do it for last 3 years

 

[karappo]

In my country, a certain corrupt politician who runs a local red cross organization makes a big buck selling blood donated for free by volunteers from all across the country. Since then I stop donating blood and would only do so if it's a direct donor-to-recipient with no middleman making a buck in between.

 

[Draugadrottinn]

Only B-types read this manga? I'm also type B (+) and I have been a blood donor at my local hospital for over a decade. 500 ml every three months here, I don't get paid but I get to choose a gift each time (donated by various companies). I choose a Moomin mug every time, they always have many of those. So now I have a decent collection with some limited editions.
Only about 8% have type B in my country, so there probably isn't that much demand for it. Maybe some goes to Eastern Europe where somewhere around 25% of the population have type B. I don't really care what they use it for, I see it as a kind of community service.
Also, I had quite a bit too much iron in my blood and blood donation has managed to reduce that to a safe level. Apparently the iron content makes my blood high quality, that's what the nurses say at least.
