Maybe for short periods of time, like to undo a mistake or relive an exquisite moment. Most of my past life, I would not want to revisit. I'm happier now than I've ever been and looking forward to continuing in this way into the future.

And one's leg muscles would develop rather differently...

Or if you had a clock spinning it's hands backwards in one room and that was your time room. Step in one door of the room and then out the other and make a Wall St. investment. Go back to your time but keep doing this. When it is found out that you are filthy rich it appears to have been some wise relative in your past.

Funny and interesting idea. There are some things I left behind and wouldn’t want to run into them again. I would love to see my dad again however.

Time in backwards went you backwards walked you when, if nice be it wouldn't.
