Count of generations

If I take my maternal grandparents as generation 0, then already my family has generation 3 and generation 4 family members who are the same age (actually some generation 4 who are older by a few years than generation 3).

Is this just an anomaly of the modern age with extended maternal and child survival compared to the norm over 100K years of human existence? 

When geneticists try to estimate generation counts over aeons, I wonder what models they use.
