Now, there are early indicators that the identical phenomenon could also be rising in Japan, a putting growth in one of many world’s most aged populations, suggesting that the downward development is changing into extra widespread…
Whereas emphasising that the explanations for the discount in incidence usually are not but absolutely understood, Hofman believes higher cardiovascular well being is prone to be a big issue given the confirmed hyperlinks between the 2.
Right here is extra from Sarah Neville on the FT. Possibly that’s the place the Flynn impact has been hiding!
