I'd die trying to figure out the best way to kill myself. There are so many choices and I just can't decide I'd spend hours, days weeks and eventually I'd die of lack of food, water and sleep.
OR
I'd go to switzerland and us the tool to brake into the LHA and fuck shit up enough to create a black hole which I'd than proceed to jump into. I will be the first human to die by black hole, but billions more will follow.
