I would test it on an animal for at least two years then wake it up and then have tests and studies ran on it to make sure it is okay.

Then I would convince my mom to enter it for a year then come out and live for a year. Hopefully doubling her time on earth (unless she passes between slumbers)

Then after that I would try to sell space and maybe charge a price to allow people to use it to extend their time on earth.

Lastly when I’m much older I would use it like that. Live a year then skip a year and do that till I die
