This world is incredible. You want it? Work for it. You want to not want it? Work towards that.

There's a number who intend and even succeed at such amazing things, the people you speak of, and inquire if we're jealous.

Metalheads at a concert, having gotten half off their tickets in echange for donating blood. It poors into buckets from their arms. All on stage, surrounded by fire. And lightning.

The procedure is as safe as ever, or at least follows protocol, except that it's being done also as theatrics, but the blood is real and revered and will help mend lives.
