Often, when we think about our bodies, we think in terms of how we look – our size, shape, muscularity, fat, and other physical features such as our hair, skin, teeth, and face. We tend to focus less on what our bodies do for us, such as carry a child, perform labor, walk our dog, digest food, observe a beautiful sunset, read and comprehend the ideas in this workbook, engage in a deep conversation, enjoy a massage, hug the ones we love, feel and express empathy, heal us from illness, breathe in oxygen, keep our hearts beating, and more. In short, the functions of our bodies keep us alive – not just physically but also emotionally. Body functionality is everything the body can do or is capable of doing [1], and can be different for everyone based on physical abilities and limitations due to illnesses, injuries, development, aging, and surgeries.
