That's pretty much what happens when you get a stemcell transplant. Luckily there is steady improvement in the survival rate. This is a very old therapy by now of course. But let's hope the various form of immuno therapy take the same trajectory, getting a little better every year.

Hank Green just did a follow-up about a question about “who has the most DNA”, where he back pedaled heavily on his previous attempt to answer.

I learned, as he had, that sometimes bone marrow transplants don’t take and one option is to administer another, or several, which could make you much more chimeric than the average stem cell recipient. But I don’t understand how the marrows don’t end up fighting each other in a death match. Is that a special property of marrow?
