Since my ability to swallow has been impaired due to the cancer treatment, I consume large quantities of water at mealtimes, along with several bottles of water throughout the day. Even so, during hot weather, I've found myself getting dehydrated. As a carpenter years ago, I use to walk on 2x4 walls without any problems. Until 15 years ago, I never fell, easily catching myself if I stumbled. Today, I often find myself tipping over, and age has made it more difficult to catch myself. Until I got my BP meds straightened out, I fell too often, and I am still concerned about doing so. I don't bounce like I used to.
