On the original question, who the fuck knows, just have a good time, balance between play/partying and good eating/exercise habits. You don't want to contribute to your demise, but don't deny yourself of things you like because it might kill you. I smoked weed and cigs for 30+ years (quit the cigs a few years back) while also exercising and eating well, you'd think I would have gotten lung cancer, instead I got lymphoma, which they tell me was triggered by an infection I got from a fly bite (really??). Point is, you never know how things like smoking or partying will affect your body, and random/chance events can kill you in a minute. So fuck it, balance shit as much as you can, don't contribute to bad health on purpose when you can avoid it (like smoking cigs), or at least try not to.
I've had a couple of close calls with death and imo your time here is pre-determined, if I knew why I probably wouldn't share it but I do believe that. The main thing from my life experience is to live your truth/beliefs and don't leave things unsaid with those close to you. If you have no regrets in how you lived your life, death is just an inevitable part of life and you won't fear it.
On a less serious note... pass that dube!
