Ayanna is a divorced middle-aged woman who has a stressful job, two teenaged children, and an aging mother to care for. She would like to start exercising to reduce her stress level and improve her memory and thinking. Now that you have read this chapter, what would you tell Ayanna regarding exercise?

I would recommend an exercise that put more focus on flexibility such as yoga.

Explanation:

From the excerpt above, we can conclude that:

- Ayanna does not have much time to exercise  since she has to take care of her children, mother, and her own job. So long cardio session is an unlikely option.

- Ayanna's main purpose for the exercise is to reduce her stress level and improve her memory and thinking. Not a strong/muscular body. So we can safely eliminate the use of weight and high intensity exercise.

Yoga is a perfect a perfect exercise for Ayanna. It can typically be done within 15-20 minute. During the process, many Yoga teacher will tell you how to incorporate meditation during the exercise. This will help her reduce her stress and improve her memory/thinking

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.
