I have to tell you that I'd rather the person who operates on a heart or a brain or flys a 777 (and there are many more I'm just picking a few obvious ones) focus on their job 100% and get rest to function at a top level. Then those people should probably think long and hard about having families, right? I'm of the opinion that if you really want to devote yourself to a career, you should skip having kids. Interestingly, the same traits that help in career advancement (hard work, willingness to sacrifice) are the same traits that help foster a successful marriage and family. Certainly, a few people can pull off both, but I suspect those people are the exceptions, not the rule.
