You skip vaccines

Grown ups need shots, too, but many of us don't get them—raising our risk of contracting a host of unpleasant, deadly—and preventable—illnesses, from the flu to cervical cancer to shingles. Just one in five at-risk adults under 65 received the pneumococcal vaccine, for example.

Recommendations for adult vaccine coverage vary based on age, health, where you travel and what you're exposed to, but the Centers for Disease Control and Prevention recommends an annual flu shot for everyone, and a diphtheria-tetanus-pertussis booster every 10 years for adults. Check out the full list of recommended vaccines for adults.
