What if a solution to death, old age and illness was found but it only worked on some people not everyone.

That depends on which people it would work on.

Right now people who have healthy habits and can afford good medical care are more likely to live longer, as well as those with good genes.

But what if there was a solution that worked only on people who were truly kind and compassionate? Now that could be interesting. Then, those of us who truly care about others would watch the narcissists and jerks wither and die, we would mourn their loss, and the fact that they never learned to care, and then, I suppose, we would move on. But then, there would always be more jerks coming into the world, and we would have to deal with them. Hmm.

This is just a crazy fantasy, but it was the first idea to pop into my head when I saw your question.

There is, although it's relative. It's called having money! Consequences are those in poverty die, those not in poverty live longer.

Sucks to suck.

I wouldn’t even bothering considering it. Got to go any way.

There will be a war over this.

sounds like a plot to a orwellian movie..
