What is the life of a monk really like?

I am curious to know a little bit more about the day-to-day life of Theravada buddhist monks. I am drawn to the idea of ordaining, but I fear this is only because I have romanticized the buddhist monk's life in my mind as easy and care-free; like an escape from my own life. What is monastic life like, and how do the challenges that come with this lifestyle compare with those of lay-life? I am looking for a reality check if anyone can provide it. Thx!
