Is this real?

It is just like an alternative fuel source. The title of the article is kind of misleading. But to be able to power all your gadget by your own blood would save you a lot of money. And it isn’t hurting you. I think it would take a long time for people to get on board though.

Question:
What happens if someone hits You in the arm (or yourself),and the tatoo breaks?

Damn. Probably something not to good.

It would sure be hard to return if you had a problem with it.
