I agree with you, my cousin started feeling frail and with reduced energy after hitting 45. He confessed to me that he did not have the sex drive he had enjoyed in his youthful age. He consulted a therapist who advised him to hit the gym. For the past six months, he has spent some at least 10 hours a week in the gym. Things are getting better. He confessed to me that his wife is much happier and he has once again felt that his body is getting stronger and more energized.
