Frailty can typically only be lessened through lifestyle changes, but a stem cell therapy seems to target the underlying causes of the condition, boosting the mobility of frail older people

This is cool in the abstract, on our timeline though?..

“My other thought is how difficult it is to obtain stem cells from volunteers. There would need to be a lot of volunteers to treat everyone with frailty.”

Gonna be a LOT of “volunteers” for rich people I suspect.
