I signed up for survival school. Since then, I have been running daily for pathetically short durations. But even these uber short jogs are increasing my endurance. I can feel it.
I wouldn't have had the courage to sign up, except Jessica (googler friend who quit Google to teach at this survival school) said I'll do fine.
I am becoming slightly obsessed about survival school, but am happy about this because it is making me live healthier. I eat less sugar and exercise more. How do people live healthily without a goal like survival school? That is impressive.
