Elevators
You could literally drop hundreds of feet
Escalators
These have killed people. They can swallow you.
Stairs
Miss a step and you're done for.
People
Not even going to start on this one.
Revolving Doors
How do you even judge if there's enough time! How many people can fit in one triangle!
Doors that do not indicate "push" or "pull"
Because who wants to be that loser who even screws up opening a door.
Breathing
Because everyone can hear it and it's obviously annoyingly loud. P.S. What if you are breathing too fast or too slow and you just die? Does that happen?
Swallowing
See above.
Chewing
Ok, same deal.
Ladybugs
They will literally urinate on you. That's cruel.
Leaving my flat-iron on
It has auto-shut off, however, it could burn the place down through heat safe material within the 30 minutes before it turns off. But only if I leave the house.
Leaving the house
So. Many. Bad. Things. Could. Happen.
But I'm okay with planes though
