Once you cross 30 years of your age, you should start taking care of your health more. The body and metabolism are not the same. We are living in a hyper-connected world with a continuous flow of information. It affects us adversely. We are social animals which result in impulsive drinking or smoking. With the advancement of mechanized foods, we are no more eating healthy.
Take care of yourself if you want to live peacefully in the later years of your life. Eat well, be healthy, exercise, sleep and stay away from tobacco and alcohol.
We all will die in the end, but getting old gracefully and decaying is better than sucking doctors and hospitals with age.
