Google up "Ranger School" and you'll find an interesting article on Wikipedia with this wonderful quote---

Physical effects
Following the completion of Ranger School, a student will usually find himself "in the worst shape of his life".

Military folk wisdom has it that Ranger School's physical toll is like years of natural aging; high levels of fight or flight stress hormones . . . . , along with standard sleep deprivation and continual physical strain, inhibit full physical and mental recovery throughout the course.

This is was certainly true for me. I could not have passed the Ranger PT test if they gave it prior to graduation. RLTW
