Daddy lessons are my series of what I am teaching my children. Daddy Lesson #4: Your physical health is everything, without it you can do nothing.
Healthy eating is the most important starting point. It is also the hardest. Eat vegetables, fruits, fish, birds, some red meat. Try to leave it at that. Foods containing processed sugars are toxic.
Exercise is vitally important. Walk every day, run some if you can. Do not run marathons, those injure your heart. There is no need for thrill seeking like rock climbing, a fall that injures you can end your life or end your enjoyment of life forever. Better to enjoy the simple pleasures of just being outside and hiking.
