Real estate looks to be in a bad spot right now. Health care is only going to grow, with aging baby boomers. Health care seems a lot more like doing something that will leave the world a better place.
I would be more worried if real estate was boring and stagnant. Real estate looks bad right now, I'll admit, but oftentimes a shakeup is useful for companies entering the market space. (Decouples people from old methods and products, and also allows for new business processes).
