The Infertility World Is the Berkshire Hathaway of in Fertility

Dr. Sherman Silver: I'm an infertility doctor from St. Louis, and I've been a shareholder in coming to this meeting for 23 years. And they sometimes compare me in the medical world. Infertility world is the Berkshire Hathaway of infertility because I'm so old and I come from a relatively small community. But I'm wondering about your interest in not just Apple, but all of the tech stocks like Amazon and Google,. Because you've stated in the past because they're complicated, you should stick with something you understand. On the other hand, Amazon and Google have what you call a very durable, competitive advantage.
