I wonder how it would feel for the first time using it.

I wonder if the vest can harm the human body? Because I mean for the person to be able to feel all those emotions that that main character is feeling then there must be a lot of technology to create such a device. If used too much, could the vest cause harm to your body then?

One problem is the size. Normal books aren"t that big. Those books are really big. I would like them to be smaller.

It is true that sometimes this wouldn't come in handy. For example, The Fault in Our Stars is an amazing yet depressing book, which would cause a lot of people to be sad... But I still want it.
