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.
It is a good idea to develop a habit of eating large meals at least 3 hours before you start your workout session. You can start working out a couple of hours after eating if your meal size is on the smaller side. It's usually fine to start your workout after 45 minutes of eating light snacks. You can sometimes have light snacks even during exercise.
