3. Dental care and hygiene
People who take care of their teeth regularly boast better health. Brush your teeth with good tooth paste. If possible, do it after each meal. Use a soft brush in order not to damage the enamel. If your gums or teeth need more attention, see a dentist.
4. Read various literature
How young you look also depends on how young you think. Do not let your brain get old. The best way to keep in good intellectual health is to read books. Pick various genres and get interested in various spheres. Novels, poetry, science fiction and biographies will both entertain and educate you.
