 As we get older, we have a tendency to eat less protein. And how does it show up? Your skin starts getting thin. You know, blood vessels start sticking out on the back of your hands. Your face starts to get hollowed out because you're not getting enough proteins. So when we're talking about the ligaments and the tendons, the cartilage, the fascia, they get less elastic the older we get, which means we need a good source of protein the older we get.
