Does this mean that donating blood reduces your number of white blood cells, and hence your life?

  My vague understanding is that your blood stem cells are in your bone marrow.

    Yes, but the article suggests that the amount of blood they can produce is limited in your lifetime before they burn out. So the question still stands: does donating blood mean a shorter maximum lifespan, because you can no longer replenish your own blood cells?

      Next we'll have conspiracy theorists claiming that blood-donation drives are a conspiracy by the 1% or the rich to kill off the poor!!

      Hmmm, my guess would be probably not? The internet says that white blood cells only live 3-4 days. If you donate 1 of your 10 pints of blood every 8 weeks, and your body actually replaces the white blood cells immediately (instead of just being down 10% for 3-4 days), you would only be increasing white blood cell production by about 0.7%.
