Tons of drug tests on children to know the exact effect they have on development. Also anti-aging research to see how much you can potentially slow down aging and how the self repair mechanism of children works with respect to aging. The results could really give us a great insight into aging well and being healthy later in life.
To clarify, I don’t want to see them done, performed, do them myself or anything adjacent because they’re deeply wrong and dangerous.
That theory is very outdated. People found out that telemeres are important but not the main driver of aging. A lot of research is Nov going on with senescent cells and epigenetics which looks more promising.
