IAmA Request: Aubrey De Grey (Ending Aging)

I think that he would help describe the process of aging and what effects can be stopped. Also explain specifically the therapies he talks about and can be useful against aging. What effects on the mind could anti aging have? Could memory be useful for someone living over 1,000 years. Hopefully someone could get this done I think it would be really useful for people interested in him and the field itself.
