Bone density
Legal disclaimer: Since we are not doctors, never follow anything based on health-related topics on this or related sites without first consulting with your doctor or other trusted health professional.
Bone density is a big issue when aging, with osteoporosis a serious issue that can lead to fractures and hugely reduced quality of life (e.g., a broken hip). It mandates attention from anyone interested in leading a long and healthy life. Women are most at risk, but men also should be paying attention.
My bone density declined by several percent from 2007 to 2011, which is something I’ll want to monitor. Generally speaking, cyclists are at some risk of bone loss, because cycling is not weight bearing and is also free of vibration and impacts, which stimulate osteoplasts.
