How would I die? That's an interesting question. You have to know what you plan on doing later in life to answer that correctly. People usually just give cop out answers like drunk driving or killed over seas if they're military. Military becoming more and more likely for me, if I do die it'll probably be incredibly quick. If it isn't quick, I doubt I'd die. If it's not in the military, probably of old age or some accident from a hobby.
Funeral? Family. Friends. People that wish to come. There's no such thing as a fun funeral. I'm old enough and have been to more funerals than an 18 year old should have to go to. Cherish your friends and family while they're still with you. Others might not be so lucky. They're somber events for a reason. While I don't want it to be sad, I do want to be remembered.
