The tangible parts of you, your body, muscles, and bones. The part of your that registers pain, the power-plant that provides you energy, and one of three parts that cultivates and produces your emotions and desires. You only have one, and though science and tech has got to the point that parts of it can be replaces, it is better to take care of the one you currently have.
Neglecting or abusing your physical self can easily effect your mental, spiritual, family, social, community and productivity initially and eventually an indirect effect on your personal finances. The biggest thing is your ability to function, focus, and move or take action.
Not only do I think of this as working out, but also what you put into your body: food, drugs, medication, and the registration of human contact (physical touch). You need all of that, in the proper proportions and at the correct times.
