At 55, I consider myself pretty healthy and plan on doing everything in my power to see 100. I take no medications with the exception of supplements, I exercise six days a week, I use sunscreen 365 days a year, I get plenty of rest, and I’ve kept to a vegetarian/vegan diet for 30+ years. I went to grad school at 50 and am thoroughly enjoying my first career as a clinical social worker after decades as a stay-at-home mom. I try to balance a busy work week with an active social life, and living in wine country makes weekends an enjoyable adventure. Life is good…and yet, I worry about aging. Aging as an amputee, to be specific.
