Marty McFly

Go online and find someone with the same name as you. Call him/her. Speak about absolutely anything. When your finished you'll feel like you lived through that scene in every time travel movie where they go back in time and they are warned not to meet or touch their other self in that time period because they will mess with the space time continuum. Also if your sick in the head you can try to see which version of you is most successful.
