| 0:04.8 | Hello, my friends. Welcome back to the podcast. I'm your host Vanessa and I am so excited for today's episode because I wanted to record a slightly different kind of episode today, something a little more personal but still very much grounded in science. |
| 0:22.1 | Now, if you follow me on Instagram, you may have seen my announcement already. |
| 0:27.4 | I'm going to get into it, but I have a personal announcement to share, |
| 0:31.0 | and then we're going to talk about the five biggest lessons from different studies and different conversations with guest |
