Homebirth was one of the best choices I ever made. We've been having babies for far longer than we've had hospitals! And keep in mind that a lot of the complications that come up in births happen because of the medicalization of birth.
However, it's worth mentioning that in all previous generations, we were outside most of time and were used to a much larger range of movements, including a ton of squatting. Mobility and certainly diet as well - probably factor into how easy it is for different women.
