ITT: One half providing helpful insight into healthy physical activities, the other half total assholes ripping into this person for not being a jock.
Some people have been living sedantary life styles, the reasons for such can range from lack of interest to mental illness. Some people get a good dopamine hit from exercise. For others, exercise is a pretty miserable experience.
If someone is reaching out to seek advice on how to improve their lives, lend a helping hand. Please don't be an asshole.
