An infection because of my own clumsiness or me doing something stupid so I break my neck.

Not really.. It would be a rather quick death. One of the worst ways to die is either by fire or falling from a great height. Sure the falling is over rather quick but in those 2 seconds it takes for you to hit the ground, you'll more then likely be terrified.

Fire is quicker then falling? Do you know at which speeds you'd be falling? Sorry, but falling would be a lot quicker then fire. Fire will first start with your hair, burning it straight off, then your skin, muscles and if you haven't fallen unconscious by then by sheer pain, you'd have to endure your insides spilling out and burning. Fire would also literally boil you.

If I had to choose between burning or falling.. I'd go for the 10th to 20th floor. Just to make sure that I'm indeed dead on impact. Of course, if something like that were to ever happen, I'd rather find a way out of the situation then die none to less but still..

I think the one that will kill me in the future is my ignorance.

The more i dont pay attention and have full knowledge on something, the more chances on a certain lethal action will be your cause of death.

Being too confident and being a risk taker.

Most probably my procrastination. It's been getting out of hand lately (and it's getting really annoying). Maybe my pessimism too.

Humankind

sickness, probably.

Gravity.

Always gravity.

I will die watching pewds in future videos and die happy

I will be really drunk or high and will decide to cycle home and probably get into a crash of some sort.

Poisened food, most likely.

marriage, and technology

Old age
