Hi, I m 40 and these last 4 years I noticed that the elastic ring on the top of my socks leaves a quite deep I think (about 5 mm) dent when it used to be about 1 mm. What changed these last years is that I attempt to run-walk 4 miles once a week or 5 days, which I haven t done since I started working and smoking about 20 years ago. But I now am unemployed and live a sedentary life. I also quit smoking and try to avoid as much as I can some of the bad stuff(fried food, processed sugar, dairy, breads).Thank you for your time.
