Okay but assuming the other laws of the universe remain in play, if light has been slowed down 186 times, then you won't be walking 3 miles an hour you will be walking 3,000 miles an hour, and anything you do to people will be unbelievably violent.

Like if you walk into the shower room where girls are showering and play with their breasts, after time unfreezes they're probably all going to die very quickly or at the very least suffer horrendous damage.

If you slap the kid that picked on you in 6th grade, his head may fly off or his spine may snap at his neck but one way or the other he's most likely going to die.

And even after you revert time to its normal flow, everywhere you have gone is going to suffer multiple shock waves as the air your body has displaced and the vacuums you have left behind in your trail collapse back together.

Doors that you've opened will fly off hinges. Windows you have closed will shatter.

But thank God you chose only 1/1000th speed. If you had chosen 1/100,000th, you might have destroyed the entire planet.
