Physical activity, morbidity and mortality in twins: a 24-year prospective follow-up

@DanielBerglind Especially this study: https://t.co/5azBCRL9ot Although it seems they have rather few MZ twins. "with no mortality difference among the smaller number of discordant MZ pairs"

@kevinnbass @Drlipid @PeterAttiaMD What are you basing this on? Rodent genetic studies we discussed only looked at mortality; https://t.co/InZpJW9uSy found no sign. difference in diabetes, HTN,CHD,or mortality in mono-twins per exercise status, and https:/

@FitGreyStrong @kevinnbass @SamueleMarcora @whsource I pointed to this and related studies yesterday: https://t.co/Td5LC9YtY2 The suggestion is that the epidemiology may not be revealing causal effects of CRF *or* training, but to underlying genetic robust

@kdinbburg @whsource @kevinnbass Yes, but people w/these conditions & are still healthy enough to exercise and have/maintain high CRF are different from those who aren't. Some surprising findings: https://t.co/M4FwMibgrQ https://t.co/fXIEQ5aCYV https:/
