The results even suggest that the most frequent donors may live longer than those who have only given blood a few times. "My response to the results is primarily of relief. Those who have donated a lot of blood live longer than those who have donated a little, and there is no evidence that it is dangerous to donate blood," says co-author Professor Henrik Ullum from the University of Copenhagen, Denmark.
