Engage your mind and spirit. Stay sharp and mentally enriched by reading and writing, doing puzzles and playing games, taking classes at a community college or online, engaging in arts and crafts, playing and listening to music and traveling — even if just taking short day trips. Seeing and experiencing new things can make you feel youthful. Immersing yourself in a hobby and engaging in lifelong learning not only can help you stay young at heart but can help you remain mentally and physically healthy, too.
