We are back! In the second episode of Info Under the Radar we are going to dive into the world of wearables. In the last 4-5 years smart-watches, smart bands, health and fitness bands have become an integral part of many people's life. So like us, we hoped that you'd be curious to know about a thing that is attached to your body and is collecting your health data without you even realizing it.

We invited Mr. Greg Kemnitz, Senior Engineer from Google Fitbit, to discuss the tech the goes behind. Greg also happens to be the co-creator of the one of the most popular databases in the world, PostGres. He has lived most of his life in silicon valley, like even before it became 'The Silicon Valley' and HBO decided to make a show on it... basically Greg is a Silicon Valley OG! Thanks Greg for joining us!

We touched upon, difference between smartphone and smartwatch, how does the sleep tracker really works, how are these wearables helping us in being more considerate of our health, nature of the data from these smart-watches/bands to the privacy concerns we have and many more. 

Don't have entire hour to commit to us, we got your back! Here are Timestamps to help you decide which part would you be interested in...jump and scroll like a monkey:
