Does this mean that people who give blood are losing valuable stem cells and wont live as long?

  There are plenty of people over 100 who could be studied: https://en.m.wikipedia.org/wiki/Centenarian https://en.m.wikipedia.org/wiki/Centenarian

  There aren't really stem cells floating around in the blood. The donation would likely still impose some cost on the stem cells though (I doubt anybody has much of a handle on that cost). There is some evidence that frequent blood donors live longer than occasional donors. Being healthy is a selection criteria for blood donation, so it can be hard to study the impact. http://sciencenordic.com/frequent-blood-donors-live-longer http://sciencenordic.com/frequent-blood-donors-live-longer

    Interesting. I looks like there are Peripheral Blood Stem cells, as opposed to those in your bone marrow. http://www.bloodjournal.org/content/bloodjournal/98/10/2900.full.pdf?sso-checked=true http://www.bloodjournal.org/content/bloodjournal/98/10/2900....

  Women "give blood" monthly and tend to live longer.

    Women who 'give blood' are also all the same biological gender. It's more than a small confound.
