Being deficient in sex hormones is not conducive for a long life. It doesn't mean a 55 year old should necessarily have 1200 ng/dL testosterone, but supplementing up to a normal range is a very good idea for bone health, the ability to exercise, and put on a reasonable amount of muscle so that you don't break a hip from falling when you're 65 or 70.
