This episode starts with a look at some surprising findings. http://www.shape.com/lifestyle/mind-and-body/5-signs-dehydration-besides-color-your-pee
Language controls what you think and how you think it. Imagine how differently you would think if you didn’t have words like “left” or “right”? Or what if your language had no specific numbers? Well it turns out there are languages like that. And the differences in languages, including English, frame the way you think according to Lera Boroditsky who is a professor of cognitive science at the University of California San Diego. She has a fascinating TED talk on this subject which led me to her. Here is the link: https://www.ted.com/talks/lera_boroditsky_how_language_shapes_the_way_we_think

People tend to ask for help all wrong! Humans like to help, we get joy from helping and if you ask the right way, you will often get the help you want. It’s HOW you ask that really matters. Social psychologist Heidi Grant, author of the book Reinforcements: How to Get People to Help You https://amzn.to/2MRA4Ep has explored the research and when you hear what she has to say, you will become better and more effective at asking for help.
How you prepare some food has an impact on how healthy it is for you. For example, you shouldn’t cut strawberries until just before you eat them – but for garlic the opposite is true.
