I've had Whoop for 2 years now and I'm using Bevel - the biological age would be great!

I would like to have it as well, please

It would be interesting to be able to see the biological age

EAGER!!! Bevel is GOAT.

This would be a great addition! Would be nice to be able to see what metrics are affecting it in which way, that way you know what to focus on to improve.
