In short, a herbivore man is a Japanese coined concept concerning men who refuse to compete for sex, romance, money and social status, in a society where pressure is too high and chose to stay single and have a quiet life.
What are your impressions about this category of men?

Personally, I feel like one of them and I'm happy to be, since retiring from the race allowed me to live happily and improved my mental health.
