For the first time in our almost 18 years of marriage I heard the word " diet " come out of my husband 's mouth . In all our years together he has never expressed a concern about his weight . It seems though that his summer of living in a hotel and eating all his meals out has caught up with him .

Question: Why is the narrator 's husband eating more healthy ?
Answer: He wants to train for a sporting event .He wants to help his heart .He wants to lose weight .He wants to train for a marathon .
