If science cures aging and disease, would you be much more risk averse?

It was a long time ago, but I remember reading Larry Niven's "Tales of Known Space - Safe at Any Speed" about a future society where aging is stopped. All I remember was that safety became very important even to the point where a vehicle protects a passenger after being swallowed by a giant bird on an alien planet.

It made need think that it would kind of suck that one would only die in some kind of unnatural death like an accident.

I wouldn't change a thing.

For me, life is about quality and not quantity. There is no value in 200 years of life spent sitting on a couch.

In a more scientific sense, I would imagine that any world where we've cured aging and disease would have significantly better trauma care, car safety, and so on. I like my odds being out in that world.

If those things were "cured" and a person could live to 150, or 200 or more, it would likely spell the end of the planet due to over consumption, over population, depletion of resources, etc. So you'd need to choose your way to die somehow.

People will be miserable :)

Yes, I like to live and not wait to die
