(see htn elderly HYVET nejm 2008 in dropbox for access to HYVET) --from 90 primary and secondary centers in 13 countries --all patients had no clinical diagnosis of dementia, mean SBP of 160-199 mmHg and standing SBP ≥ 140 mmHg     --mean age 83.6, 60% female, mean sitting BP 173/91 mmHg, followed mean of 2.0  years;     --study found large reductions in stroke, death from any cause, death from cardiovascular causes, and rate of heart failure --cognitive function assessed by the Mini-Mental

exercise helps mental health

​ A recent large study confirmed the benefit of physical exercise on mental health (see  exercise and psych health lancetpsych2018  in dropbox or doi.org/10.1016/ S2215-0366(18)30227-X).

aspirin in healthy adults: harm without benefit??
