Hello, I hope this helps you.

Answer:  Pollutant advisory warnings should be ignored.

Explaining: If someone is concerned about the effects of the pollutants on exercise, then they should definitely not ignore the pollutant advisory warning. Most of the people exercise in the open environment and breathe very deeply through the mouth, the air people breathe in generally bypass the nasal passage and affects the health.  So, a person who is interested in exercise should never ignore the warnings so as to maintain a good healthy body.

Answer:

There are plenty of great benefits that come out from working out and eating healthy foods. From better hygiene to a better body shape/size, there are so many! Salads might be gross and all (I, for one, stand by that), but they can actually help you get more fit and look better, compared to eating Hershey bars all day. Foods like hamburgers and fries from McDonalds, Burger King, etc. won't help at all. Try to resist the urge, if you ever feel like getting one too many! Besides, drinking sugary sodas can lead to cavities, which will cost you hundreds of dollars to fix up-just for something that probably cost you less than half your allowance. (Not-so)-fun fact: People with cavities/dental issues are less likely to get into a relationship, according to studies. And I don't know about you, but it'd get pretty lonely in there. That's all I got. Hope it helps! :)
