NEW YORK, New York (The Adobo Chronicles, New York Bureau) – Greta Thunberg, the 16-year-old Swedish climate change activist may be suffering from progeria, the premature aging disease.

This was the conclusion reached today by an international group of medical experts meeting in New York City for their annual convention.

The experts, however, said that Thunberg’s case is unique because her disease affects only her thinking and speaking, not her physical appearance.

The teenager recently made headlines for her angry, impassioned speech before a gathering of environmental officials and advocates. She accused adults of ruining her childhood by their inaction on climate change issues.

’”She looks like a 16-year old, but thinks and speaks like a 60-year old,” the experts said, “and that is a clear symptom of pre-mature aging.”

They, however, hope that Thunberg’s speeches are mere scripts prepared by other, real 60-year olds, and not really her own.
