You have powerful recuperative powers which enable you to survive the ravages of many illnesses. Most Leos are noted for their longevity, so you can reasonably expect to live to a ripe old age unless you abuse your body foolishly. You can become emotionally involved in other people's lives and the consequent worry can cause stress and pressure which is harmful to your well-being. Just to be on the safe side, you should have regular checkups with particular attention paid to any peculiarities of the blood which can be vulnerable to problems for Leos.
