Who Sells Longevity Annuities? 
Longevity protection is a good definition for an immediate annuity . I have not heard that word longevity used as a description of an annuity . An annuity provides money that the annuitant can not outlive . At the same time it provides for the highest consumption . So you have high income and can not outlive your asset . That sounds like a longevity annuity to me . These are sold by licensed life insurance agents .
