John, it's great that you want to learn more about those topics. But, don't misunderstand. Earning a PhD is like 10% learning about the topic, and 90% learning the process of research and the business of research. Based on your blog post, it's going to take a while until that other 90% really hits you. Reading papers is easy compared to writing them.

Also, PhD studies and the academic life at a research institution are emotionally stressful and extremely time consuming. You have to consider the negative impact of that on your family, regardless of how supportive they are.
