 Testing hypothesis is the whole life of a scientist. We need to understand what is the need to be addressed or the question that is open. We need to create the answer for this question that is the hypothesis, and you need to test your hypothesis. If your hypothesis is right, you are ready for the next level. If your hypothesis is still not completely right, you need to come back to the question and maybe readjust the answer, and that answer is the hypothesis. So we need to create new hypothesis to try to move the knowledge moving forward. And the best thing that we have as a scientist is understanding that knowing and thinking about questions every day and trying to address these questions every day with different hypothesis, you can consolidate established knowledge or you can create a new knowledge. And that is the most exciting part to be a scientist is exactly accumulating knowledge and supporting some previous information with your new discovery. So science is discovery. And discovery is the excited part of the life. We can understand new points of view. We can understand new systems and you can find specific approaches to treat a specific disease. And this is what the Texas Heart Institute is focused on. How we can use the research to address the questions that will help the patient that is in need for now.
