Body surface area. In physiology and medicine, the body surface area is the measured or calculated surface of a human body. For many clinical purposes BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass.
A life estate deed is a deed in which you transfer the future ownership of your home but retain the current ownership, creating both a present interest and a future interest in the property. You, as the present interest holder, have the exclusive right to enjoy and live in the residence until you pass.
A legal life estate in real property can be created by conveying the property by a deed which carves out the life estate for the grantor and creates a remainder interest by which the remaindermen receive full ownership (fee simple) immediately upon the death of the life tenant (grantor).
