“When you’re over age 65, your immune system isn’t as strong as it used to be. Seniors make up the bulk of the people who die or are hospitalized for flu-related problems like one being pneumonia to sepsis.  Getting older can be a triple whammy. You lose muscle as you age. That makes it harder to keep the pounds from creeping up. You also become less active. At the same time, your body burns fewer calories for the same physical activities as when you were younger.  Our nutritional needs change as we age. Many of us don’t eat as well. Plus, older bodies can more easily lack certain vitamins and nutrients.  Also, bones become less dense and more prone to breaks and fractures.  Did you know that age is the single biggest predictor of your chances of getting cancer? It jumps up after you hit age 50. Half of all cancers happen in people over age 65. For lung cancer, the median age is 70.  Still getting older doesn’t mean you’re destined to get cancer. You can adopt healthy habits proven to help you lower the odds.”.
