Life’s rewind button
There is a life rewind button.
No it is not a mechanical or electronic device, it requires a memory, a focused memory, and a glass, or two, of your favourite beverage. You need to make sure that your forward thinking is firmly switched off because that way can trigger pain and grief. Then you can recall some of the better moments of your past life. Some will be but a short recall others much longer. Some will be but a fleeting memory other will be enduring.
