But why wouldn't we be able to evolve resistance to bullets? Toss
enough airgun pellets about, and we'll likely evolve thicker skins (or
faster reactions!) just the way we evolved sickle cell anaemia (gives
malaria resistance) and cystic fibrosis (Cholera).

And in time we'll become .22 resistant... DU cannon shells might take a
while though.

Bacteria of course do all this _much_ faster.

I'd have to remain sceptical of this idea! But it's an entertaining
thought!

It would be far more efficient to measure skin thickness and sterilise those
with thin skin.

Likewise we could extend human life by sterilising the off spring of those
that don't live a long time.
Its too late to do anything after the breeding period has passed so you have
to tackle the off spring.
