Kane Tanaka (119) since today the second-oldest human ever: where is the limit?

The oldest woman in the world Kane Tanaka is 119 years and 97 days old today. This means that the Japanese woman is exactly the same age as the American Sarah Knauss on her death day in 1999. Only the French woman Jeanne Calment (122 years and 164 days) who died in 1997 has ever grown even older. Are we getting older? And where is the limit?
