This popped up in the New York Times this morning but I didn't link it because the criticisms seemed apt:
Brandon Milholland, a co-author of the study finding a limit to human life span, questioned the new paper. The research, he noted, was limited to just seven years in one country.
“You’re reducing yourself to a narrow slice of humanity,” he said.
Dr. Milholland also took issue with how the team analyzed their data. They only examined two possibilities: that the death rate continued its exponential climb, or that it turned into a flat plateau.
The truth might be somewhere in between, he said: “It seems rather far-fetched that after increasing exponentially, the chance of dying should suddenly stop in its tracks.”
But then, this ain't my wheelhouse. Care to comment?
