Exercise B

                                                 Skin

Don't smoke. Smoking makes your skin look older and contributes to wrinkles. Smoking narrows the tiny blood vessels in the outermost layers of skin, which decreases blood flow. This depletes the skin of oxygen and nutrients that are important to skin health.

                                                Bones

Pay attention to vitamin D. Your body needs vitamin D to absorb calcium. Good sources of vitamin D include oily fish, such as tuna and sardines, egg yolks, and fortified milk. Sunlight also contributes to the body's production of vitamin D.

                                                Muscles

Protein. Muscles are mostly made up of proteins. It’s important to include protein in your diet to replenish what is lost during workouts. Proteins include meat, poultry, seafood, eggs, and milk products.

                                                Brain

Become a Social Butterfly. Staying close with friends and family and being involved in social activities and social situations can greatly contribute to a long life of strong cognitive health. Keeping your brain active through conversation can make an enormous difference as you age.

                                                Liver

Avoid alcohol. Even small quantities of alcohol if consumed regularly can burden your liver. The liver is responsible for detoxifying alcohol so having complete breaks regularly from alcoholic drinks helps your liver.
