    Yet residual or enlarged thymus is seen as a potential cause for autoimmune conditions like Myasthenia Gravis. And it’s often removed in these cases. So is it really good to have a thymus after 30 or not?

    Thymus involution can be reversed in humans (see TRIIM and TRIIM-X trials by Gregory Fahy).

    It seems that this intervention has a moderate systemic rejuvenating effect, too.
