My parents are 74&75(this month!). They are in great health, exercise regularly and stay active in their church, and babysit my youngest niece several times a week. They travel, help out when they can too. We went hiking in SNP this fall and to a brewery
My FIL suddenly died this year; just died in his sleep. No autopsy but he had poorly managed diabetes and a CABG 15 years prior and was 62 and MIL’s caregiver. MIL is 60 and in poor health. Totally inactive, poor diet, has CKD, balance problems, swelling in her feet and uses a walker.
