I m 77 age female and live alone. I still weedeat many flowerbeds and property along the lake. I get tired but no pain. I mow my on yard, plant a veg garden & shrubs, use an electric chainsaw, dance much and always active. All my friends are younger and less active yet tell me I shouldnt be doing these things. I feel great, have had through heart exams, etc, and told I m fine. Should I stop weed eating and working so hard?
