Rest vs Relax?

I was told that for the sake of my health that I needed rest. So I took two weeks and did my best to "rest". 

Rest included: handling a quickly growing boy, reading, sleeping, working out, watching several seasons of Fringe on Netflix, writing, running, hiking in Canyonlands, then I did some more reading, sleeping, handling a 15-month-old busy body, and then working out some more. 

That is about all the rest I could handle... 

What do you do to rest?

I've pondered a lot on this topic and thought that I would toss the question out to readers to answer. What is the difference between resting and relaxation?
