Fino alla morte
Experts in different fields of the sciences and in particular in human biology have decided upon this very question raised by the OP and that's why they were given the green light to compete with the ladies.
A better question is, will certain men (Horn of Africans & others) be allowed to compete with the ladies 100m, 200m and 400m since they have no chance competing with African American and West Indies men of African descent? Can a Farah beat those ladies?
Who says we want to compete with them? We'll stick to what we do best and blow everyone in the 800m and above :siilaanyosmile:
