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.
With a regular life estate deed, the owner of the real estate makes a gift of the property to beneficiaries, called remaindermen. He can't mortgage or sell the property during his lifetime without the permission and joinder of the remaindermen -- joinder means they're parties to the mortgage or sale.
