As we get older, we find that the moving parts seem to move a little slower and with a little less range of motion than they once did. As annoying as this might be, there is really nothing that can be done about it until science perfects the art of cloning a new young body for your tired old brain to fit into.
Until that happy day arrives, we just have to make the best of it. Sometimes, that means altering the way we have always done things. Getting in and out of a bathtub is a good case in point. Worn-out joints and atrophying muscles can make that little step quite a climb and one that can be dangerous. The solution is to install one of the many types of safe step tubs so you can simply walk in, close the door, and relax without the worry of hurting yourself.
