India's life expectancy is around 62 for men and 64 for women. People die before they get PD and then there is the diagnosis conundrum. Ethiopians have an even lower PD incidence but can expect to live 58 years. They would have to have a super high YOPD rate to catch up. Japanese have a high expectancy but terrible stomach cancer rates. PD is lower but more women get it than men where the opposite is true here, I believe. Why?
