I’d say Dev is using a rather negative approach, but this is a very personal question, based on how the reader themself views health too... However i say negative because Dev is comparing himself to a friend. His motivation to be healthy is there, but it is dependent on his Bretts lifestyle and how he looks and feels.
Brett is healthy because he is active (goes to the gym), sober (doesn’t drink alcohol), and perseverant (he has no sick days in school)
Devs health would benefit, as his weight would decrease considering he hasn’t done any physical exercise in 5 years, his feeling of being unfit and unhealthy would decline, most likely contributing to his mental health as well, giving him a better sense of security and happiness.
Mass is constant and does not depend on gravity, Where As <span>Weight is the force something exerts from its acceleration due to gravity.
Example: </span>A 100 g sample is 100 g on the earth, on the moon, wherever. <span>Since the force of gravity varies, this amount can vary greatly depending on where the thing was weighed. Even on earth the difference in the force of gravity between different elevations is sufficient for an object's weight to be different.</span>
I'm pretty sure your answer would be C) widely used in France, Russia, and China, because I know they use that method a lot.
The oldest person ever recorded was Jeanne Calment of France. She was 122 when she died. But the oldest person in the BIBLE was 969 when he died... hope this helps, friend!
