They bleed too much, they have more infections and complications. They have a harder time recovering. It's much better if they are calm. Create Balance in Your Life Be reasonable. A person who constantly pushes himself to the limit physically and emotionally is a prime candidate for burnout and possibly for depression.
Balance is the key.
Learn to say no to demands that exceed what you can reasonably handle. Do not compare yourself with someone else. Yes, even in matters of worship, God does not make unfavorable comparisons, demanding more than our individual circumstances allow. Make time for relaxation. Even Jesus, hardworking though he was, made time for rest for himself and his followers.
