I was curious how long it would take to make a sword out of your own blood. If my math was correct(it probably isn't lol) the human body contains around 4.7 to 5.5 liters. And then you can apparently donate like 470 millileters every 8 weeks.

So take 4.7(assuming the smallest people) X 300 = 1410 L total blood

1410(total needed) / 0.47(donation amount) = 3000 donations X 8 weeks = 24,000 / 52 = 461.54 years

Safely. You could probably speed it up a bit if you have a higher risk tolerance.

True! I would assume a larger person would be able to give up more at once, too.

[–] Dave@lemmy.nz 4 points 7 months ago (1 children)

A larger person might want a larger sword, though!

That's a good point. You couldn't have someone like Shaq with a 3 foot sword. It would look too tiny! Gotta size it proportionally.

Or if your enemy has been thoroughly dispatched

[–] Dave@lemmy.nz 4 points 7 months ago

This estimate was for your own blood, not your enemy's, so probably best not to thoroughly dispatch yourself.
