Really now, what is so terrible about the prospect of failing to suffer years of hideous pain, disfigurement, and disability that it forces people to wax lyrical and beat their breasts and say, woe is me, we might have the chance to not suffer and not be diseased and not be forced into a painful death not of our choice?
I mean, I believe near everyone you can find to ask is generally in favor of cancer research. That's absolutely about preventing all of the above.
But the prospect of treating the medical condition we call aging and removing its consequences? Suddenly everyone is a poet, inclined to the morbid.
