There is a mistake in this.

Indeed today Ethel Caterham enters the TOP 100, but tying with Iso Nakamura (114 years and 214 days)

And also in the gerontology wiki list they left out February 29, so there is a 1 day error.

Ethel Caterham's age as of March 22 according to the wiki is 114 years and 213 days, this is an error as the correct age is 114 years and 214 days.

Ethel is now in the top five oldest living people

This just seems really weird to me that she is in fifth place already

Ethel had to wait until 114.5 to become the oldest person with initials "EC"
