What's the death rate for people who are sensible?

Sensible how? Like not climbing Everest? Be careful how you define it, because there's the danger of saying that everyone who lived was sensible. Anyway, that's kinda like saying that drunk driving is only dangerous if you're not sensible when you're doing it. We can't survive that long that high, and our judgement becomes seriously impaired, similar to being drunk.
