Hey folks it's Ben Greenfield here and if you've listened to the podcast for any

it's called the Sweetbeat and I simply put that on and can monitor my HRV

stress levels as I'm walking around the house or lying in bed in the morning or

variability and who was behind the development of this particular measuring

tool that I use her name is Ronda Collier and Ronda has more than 25 years of

experience in high technology product development and she's spent the past

several years studying and developing health monitoring techniques non-invasive

health monitoring techniques such as this heart rate variability system that I've

been using so I figured she would be a perfect person to get onto the call

today and talk about heart rate variability with so Ronda thank you for

coming on the call. Hey thank you for having me Dan. Well we've we've talked

about heart rate variability on the show before like I mentioned so don't be
