I’m a bit suspicious of it really, don’t quite like the idea of freezing someone and trying to wake them up hundreds of years later. I understand why people would want to be preserved and maybe saved when medicine has advanced but the energy and resources required to keep people would be incredible.
On the other hand, things like seed banks that freeze lots of different species from our planet are a great idea particularly with the threat of climate change. It’s a great way to preserve plants for future generations.

Actually, I preserve the microalgae for long term storage by freezing them in liquid nitrogen, similar to cryonics. They can stay this way for a few years until I decide to “wake” them up when I need them. I always find it amazing that they can survive the deep freeze for so long!

We freeze fertilized mouse eggs in liquid nitrogen for years, then thaw them, put them into the uterus of a pregnant mouse and they will be born… many, many years after they have been fertilized.
This is a really useful way of storing special lines of mice without having to keep alive “on the shelf” which is really expensive and is also unethical.
