time travelling: why i will not do it

why i will not time travel

i for one am against the idea of me time travelling. here's why;

1. time machines aren't a thing yet: this one is obvious
2. i might embarrass myself to death: if i go back to when i was a kid, i'd think i was so stupid! (and i wouldn't be wrong!)
3. if i go to the past, i'd probably spread at that point uncurable diseases and cause THE END OF MANKIND.
4. if i go to the future, i'd probably find myself in a skynet dystopia
5. i might accidentally kill my caveman ancestor in self defense, which won't be good for my future
6. if i go to the past, they might see me in my time machine and accuse me of being a witch (which wouldn't make sense since i'm a MAN)
7. i would not make a good lunch for a velociraptor
8. i might meet my past self and cause THE END OF THE WORLD.
9. inflation in the future will make marbles cost an arm and a leg, no doubt
10. what would i even need from the past/future?
