Some want to inject fat, others want to perform a lower eyelid lift, and one wants to do nothing to this area. There is some disagreement as to whether the skin will wrinkle underneath the eye as a result of the facelift if a lower eyelid lift is not done. I would appreciate other doctors' experience and advice.
Thymus Essentials. 1  The thymus gland, located behind your sternum and between your lungs, is only active until puberty. 2  After puberty, the thymus starts to slowly shrink and become replaced by fat. 3  Thymosin is the hormone of the thymus, and it stimulates the development of disease-fighting T cells.
The thymus is the first of the lymphoid organs to be formed and grows considerably immediately after birth in response to postnatal antigen stimulation and the demand for large numbers of mature T cells. Genetic factors also influence the age of onset, rate and magnitude of thymus dependant immunological function.
