100 blood donations! That's a lot. I used to give regularly but would be 2-3 times a year. One would have to do that consistently over 30 years. Commendable!
So, are these considered useful mutations?
They analysed the blood of persons over 60. So the amount of donations accumulated over a lifetime. But you are right, they had to donate several times for many decades.
I guess in a certain context these mutations are useful. After blood loss EPO stimulates the growth of new red blood cells. So if they lost a lot of blood these individuals probably had a slight advantage because their body would form new blood cells faster compared to the controls.
