Good friends are great to have — for your mental well-being as well as your physical health. According to a New York Times article, strong friendships help fight illness and depression, speed recovery, slow aging, and prolong life. Celebrate your pals by returning the favor:

• Practice empathy. Having a trusted friend to listen and help dissolve life’s frustrations is essential to healthy living. Strive to be a true confidant yourself.

• Make time. Don’t take your buddies for granted. Remind them how much you value their relationship. Join up for a weekly hike and support each other’s healthy habits.

• Communicate honestly. Negative circumstances or feelings surface during most long-term relationships. If aspects of the friendship are bothersome, clear the air — honesty is vital. Don’t hold grudges, and be willing to admit your own mistakes.

• Be selfless. Go above and beyond. Cook dinner or offer to babysit to ease their burden during stressful times.
