According to new estimates, one in five of the British population can expect to reach the age of 100.
It won't be long before those traditional Jewish birthday wishes, "Bis hundert und swantzig"/ "Ad meah v'esrim" - "May you live to a 120", will seem out of date.
Perhaps it's time to revise the figure. How about 127, the age of Sarah, for a start?
