The eardrum may need to be replaced and various tissue grafts may be used to replace it. These include the covering of the muscle from above the ear (fascia) and covering of ear cartilage (perichondruim), or covering from the skull (pericranium).
Doctors and dietitians generally recommend at least three large meals and three small meals in a day. The time interval between each feeding will be generally 2 to 3 three hours. One reason for this is that there will be no hunger pangs, and the food you eat will be in lesser quantity than when you keep a gap of 8 or ten hours between your meals.
Depending on how heavy a meal you eat, you should wait 30 minutes to two hours before exercising. The bigger the meal, the longer you will need to wait. If you just eat a light, high-carbohydrate snack like half a bagel or a few low-fat crackers, you should be good to go almost immediately.
