Town lifestyle (I assume you mean by this: a settled lifestyle , so that it contrasts with the nomadic lifestyle) comes with more security: you can store your food reserves and plan for the future.
nomadic lifestyle gives you more flexibility but less security: you can travel elsewhere if your fodosource is runnign low... but usually this is not as good of a food source as a settled lifestyle. One other possible advantage could be being merchants: nomads can benefit from a trade.
Hey there,
Your question states: What do you conclude about the weight problem in america? Based on my research, I believe that your correct answer would be <span>The overweight problem in the adult American population isn't as bad as the underweight problem.</span> It's been recorded that many of adults fall in that category on the obese or the heavy weight problems.
Hope this helps
