“It’s all about lifestyle - the more effort you put into living a healthy life, the longer you’ll live and the better you’ll feel because of it. And while diet and exercise are critical components of a healthy lifestyle, it’s also important to take a look at sleep patterns, stress levels, nutritional deficiencies, food sensitivities and other factors that could potentially lead to health challenges later on in life.”
