I'm not totally convinced that attending parties is a good way to measure someone's health, but it might be true that people who always stay at home and don't socialize could have more mental health issues. Since we are social creatures, interacting and talking with others is important for our mental well-being. If someone prefers to stay at home and avoid others, it could lead to problems later. So, it's possible that these people might be less mentally healthy.
我不完全相信参加聚会是衡量一个人健康的好方法,但是那些总是待在家里不愿社交的人可能确实有更多的心理健康问题。作为社会生物,与他人互动和交谈对我们的精神健康很重要。如果有人更喜欢待在家里避开他人,这可能会导致以后的问题。所以,这些人可能心理健康状况不太好,这是有可能的。
