Question: Are you involved in vigorous physical activity for at least four days a week? Identify the types of physical exercises you practice or would like to practice if you do not and why. What are benefits of maintaining a healthy diet and exercising regularly. How can this affect physical development in early into middle adulthood (such as skin, hair, sensory functioning, reaction time, lung capacity, and lean-body mass vs. body fat, metabolism, etc). Discuss this in detail. Also discuss why people use illicit substances and the negative effects and impact of substance abuse in early and middle adulthood.
