I have a friend who is doing a Masters in Architecture at Yale. He loves it, but he sounds like the busiest person on the planet.

He says that they have less free time than the Med students. They get up at 7, go to class, then work in their studios until like midnight.

I wouldn't do it unless your heart is completely into it. Or unless your program is much more relaxed. But in that case, you probably wouldn't get as much out of it.

As for your 2nd question, if you have any interest in health sciences, you may want to look into Schools of Public Health. There's a ton of interesting programs there. I am currently finishing my Masters in Epidemiology.
