I had the flu and now that im better my kids have it. can i catch it again or am i in the clear?

In the clear: Unless your kids picked up the flu from some one else and is a different strain than the one you had, you are in the clear. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
