Living to the age of 110 is abnormal enough that within 6,666 people selected as a statistical representation of the population, it is extremely unlikely that anyone would live that long, much less continue performing at the apparent health of an 80 year old.

(Did you mean 10,000, not 6,666?)

I, too, thought that living to 110 was really rare, but I looked for some statistics and it actually is about 1/10,000, so the age alone is not surprising. Wikipedia says that getting from 100 to 110 is 1 in 1000, but getting from 80 to 100 is not that bad. In England, men have a 6.2% chance and women a 9.2% chance.
