Well, don't get it unless you're missing an arm. It's still expensive and you will consider it useless and throw it away. If you bought it on sale (whenever it comes out) and you want to throw it away, donate it. At least you don't waste that money and help another.

This event would be dangerous "if" they used hydrogen... It would cause a humongous explosion. Even without hydrogen, they can crash into each others, causing a few casualties.

I never knew that selfies were so dangerous! Good thing that I don't have any phone... I need to tell this to my sister!

can they evolve because I think they are still the same from the ancient days

M-city could lead to a good place, but if the cars go on gasoline and everybody relies on the technology, what if there is a blackout? Then the cars won't be signaled so they would just crash into each other or even into a building! Even if the person riding in it knows how to drive, it wouldn't have a system to let people control it!

Well... even though I know it will never really happen.

So... from when will we get things by a drone? What if it's like a pizza and the person him/herself need to pay for it? Then it'll need to go down!

The goal of this contest, I believe is to tell people that if the inner body (soul) is really good, the outer shape does not matter.

I believe that most of the contestants could have ripped their "toilet paper cloth" while making accidentally, so I think that's why the winning price is so high! Some contestants can be crying because of it.

The green light and red light... it could be a star. I heard that stars make lights differing from their temperatures.
