I'm 39 years old. Once my obligations in life are done, I'm putting a bullet through my brain. Probably just another 10 years or so this point.
It's of benefit to look after my own health but at the same time, why? By the time my poor life choices start catching up to me, it will be time to go anyways. If my health deteriorates before then, then I'll just shoot myself in the head sooner rather then later.
To me I'd rather enjoy what little time I have left indulging into a little hedonism then trying to plan for a future that doesn't exist.
