I exercise every morning. I do light weights - 5lb and 10lb arm exercises - and then lie and lift my arms and legs. It's all about keeping core strength. I do a lot of stretching too. ↗
Right now, any opinion anyone has about whether dogs can or cannot really tell when their owner is coming home by some unknown means... nobody knows. The weight of evi dence suggests they can. ↗
A raised weight can produce work, but in doing so it must necessarily sink from its height, and, when it has fallen as deep as it can fall, its gravity remains as before, but it can no longer do work. ↗
