Yup, we all die, so get out there and do stuff you love, try new stuff.

And ya, life can be dangerous, we just need to manage and evaluate risks, act accordingly and use common sense.
control the stuff we can, ie use a mirror, be situationally aware, try not to ride a narrow, busy highway at rush hour Friday, eat and drink properly and don't ride a 10 hour day so that you're so zonked that you aren't situationally aware. Etc

**** happens sometimes, but it usually doesn't.

comes down to evaluating risk really.
