From interview with the authors, why you should be a bit careful with just going ahead and trying this out "This is a somewhat invasive procedure where your whole blood goes through a machine and the cells are returned to you and the plasma is diluted. It is not completely benign, and you cannot just keep doing it every day. So, to know how long the effects last and to know it for each individual is an additional know-how part that we found out from a couple of years of research and are studying further. I’m sure there will be competition, but I just want to warn everybody, do not go somewhere and get your blood replaced with saline. Wait until there are reputable clinical trials and people know a little bit more."

> do not go somewhere and get your blood replaced with saline I just did that this morning when I donated blood. They said they needed the plasma badly, so they took the red blood cells and the plasma, and returned a saline solution. So maybe you just need to donate blood/plasma often to stay young?

  study shows that people, who donate a lot of blood, suffer no serious ill effects and may even live longer than less frequent donors. https://sciencenordic.com/body-death-denmark/frequent-blood-donors-live-longer/1425568 https://sciencenordic.com/body-death-denmark/frequent-blood-...

    Unfortunately they don't give any details on what constitutes more frequent and less frequent. For example once a month vs once a year or once very 2 weeks vs once every 2 years, etc.

      Whole blood donation generally is only allowed every 8 weeks. Double-red blood cell donation is allowed every 16 weeks up to a maximum amount per 12-month period. I believe Plasma can be safely donated every 4 weeks. Doesn't tell you specifics about the study, but know there are different kinds of blood donation and different frequencies that are permitted for each. I think it's common for regular donors to donate almost as often as is recommended.
