While surfing (searching) the Internet for issues related to health, I found a website from the National Institute of health that was full information older Americans (and anyone who knows or is going to eventually BE an older American) will find helpful. The information has the benefit of being accurate. Given the opportunity, I'd want my parents to be familiar with this informational doorway, ...if they were still with me and not part of the ancestors who make up my being. Hopefully, you will be able to use it, or can refer it to your loved ones. Enjoy. Learn. Surf.
