No one can deny that invition helps our lif to be easier. Invintors invinted many types of invintion that help us in different parts. If i could un-invint some thing, I would un-invint water heater. I love to swim in a cold water because it helps me to be fresh and strenuous. I think that many people will not agree me, but each person would un-invint the product that he will not use it.

In conclusion, we can't un-invint any type of invintion becaus i think that all invintion is good for most people, so we can not look at this invintion from our side. Also we have to look at it from other people side. invintors will not invint any thing that does not important.
