This is a very good point! Also, hormones! Ive had to take all the hormones for a long time due to a pituitary tumor. So I can make sure Im on the most even keel. When hormones are out of whack for women AND FOR MEN, it changes a lot of things. Especially moods and happiness. When they are not taken orally they wont cause cancer etc.
Good point. Mens hormones decrease and can get whacked as they age.
