Sounds like a great idea. Where can I sign up?
If you were to go back in time, you could very well change the present you left from.
If you were to go forward in time you would miss much AND be seen as missing . . . Unless you came back to the present to stick around after . . .
The slightest change could have enormous ripple effects of change . . . Not in a good way unless perhaps you had terminal cnacer.
Dreams take you forward,
memorie takes you back.
