Men finding success in doing anything physical is coming to an end. Men...it's all about brain power moving forward. Get yourself or your sons in to STEM (science, technology, engineering and math). The future is drones and A.I. If you don't know how to work with computers or robotics, within the next 5 years, you will be among the 'new illiterate' - those who don't know how to use technology to earn a living.
