[Question] Are there easy, low cost, ways to freeze personal cell samples for future therapies? And is this a good idea?

I hap­pened to come across this old post from 2015, that (in a sort of round about way) en­dorses freez­ing some cell sam­ples to­day, be­cause hav­ing frozen cell sam­ples from your youth might prove im­por­tant for fu­ture anti-ag­ing ther­a­pies.

I am some­what skep­ti­cal of this be­ing a ma­jor fac­tor for anti-ag­ing, but I won­der if oth­ers have more in­for­ma­tion.
