own your body's data

I always wanted to know, what are people trying to hide with numbers? As a statistician, I want people to show me the data so I can decide for myself. I was pregnant with third child and I was at about 41 and a half weeks, what some of you may refer to as being overdue. The doctor said, "Your chances of having a miscarriage double when you go past your due date." So now as a statistician, what's my response? Show me the data! I said,

¡°Out of 1,000 full-term pregnant women, how many of them are going to miscarry just before their due date?¡±

And then he said, "about one in 1,000."

I said, "Okay, so of those 1,000 women, how many are going to miscarry just after their due date?"

"About two."

I said, "So you are telling me that my chances go from a 0.1-percent chance to a 0.2-percent chance."

Okay, so at this point the data is not convincing me that I need to be induced. And then I said, "And I really don't think my due date is accurate. Pregnancy due dates are calculated assuming that you have a standard 28-day cycle, and my cycle ranges ? sometimes it's 27, sometimes it's up to 38 ? and I have been collecting the data to prove it."

Why was I confident that day? Well, I had been collecting data for six years. I had this temperature data, and it told a different story. We can use data about our bodies to tell us a lot of things. For instance, did you know that taking your temperature can tell you a lot about the condition of your thyroid? Your thyroid tries to keep an optimal temperature for your body. But what happens when your thyroid is not functioning well? When it doesn't function, then it shows up in your body temperatures, they tend to be lower than normal or very erratic. And so by collecting this data you can find out information about your thyroid.

There are tons of other things you could take. You could take your blood pressure, you could take your weight. By taking ownership of your data just like I've done, just by taking this daily measurements about yourself, you become the expert on your body. You become the authority. It's not hard to do. You don't have to have a Ph.D. in statistics to be an expert in yourself. You don't have to have a medical degree to be your body's expert. Medical doctors, they're experts on the population, but you are the expert on yourself. I challenge you to take ownership of your data. And today, I hereby confer upon you a TEDx associate's degree in elementary statistics with a concentration in time-dependent data analysis with all the rights and privileges appertaining thereto. And so the next time you are in your doctor's office, as newly inducted statisticians, what should always be your response? Audience: Show me the data!
