C'mon, no one is forced to stay inside because it is dark lol....what is this the 1500's?? lol At that time of the day gyms begin to get crowded with the after school and work crowd.
And there is this new craze called working out at home. You may have heard of it during the past 3 years???? For $200 someone can purchase weights, exercise bands, and a stationary bike. Also there are plenty of people who go running when it is dark
No one, repeat no one is getting diabetes because it gets dark early.. Laziness has nothing to do with it being dark early. Laziness is a choice regardless of when the sun rises or sets..
