So I already know that a human kidney is worth $262,000 on the black market, getting a kidney removed can cost up to $67,000, and that a kidney weighs 170 grams.
Now I just need to know how much 170 grams of stem cells costs, and if it's less than $195,000 I can finally get my small business off the ground.
Nevermind, I just realized I can just steal them from people without the surgery or stem cells. I wonder if anyone else thought of this...
