i would like to present to you the "connect-a-time". this is a machine that allows you to travel back in time. it looks like a time machine but the result is diferent. the diference between a time machine and the "connect-a-time" is the fact that with a time machine you can go back as a diferent person see yourself as a human ad change the cource of history just by being there and not doing anything. if you take the "connect-a-time" - you will be transported back in time in your own body. you are able to feel the emotions you were through before and maybe even do somethings diferently. it would depend on the time to go back to. 

now i would like to explaine the reason for such a machine. i have heard many people say that they would like to go back to a certain time of their life and re-live it. now change it but be able to go through the same motions and emotions. for instance, i would like to go a few summers back and re-live the time i spent with my friends again.
