At what stage of their lives do mayflies not eat?

you eat to live unless you are a lazy person. living to eat makes you're life a lot harder.

This depends on who you are asking. Those who are poor and don't have much money to buy food eat to live. Those that have enough money and tend to over eat live to eat.

you eat to live because you need food

Take food in an appropriate and balanced way. Everything in moderation, and not through gluttony. I think it means live your life to the fullest and not live just for anything .

YES!!!
