Fact No.243

Assuming that every person has 2 parents, 4 grandparents, 8 great grandparents etc. That are all unrelated, if a family treee were drawn, 10 generations would give you 1024 ancestors, 30 generations would give you more than a billion ancestors, And 40 would give you more people than have ever lived on the earth.
