Thank you Jemma. Thank you Tyler. Thank you EVP. Not just for letting us interrupt your lives, but also for spending your time on earth working towards positive change.

In case it isn't evident in the episode, this is not an ad. We were not paid to visit, EVP had no editorial control, nor did they have a say in what we filmed. The truth is a shield. It just took us seeing them in person to figure it out.

The Astounding Physics of N95 Masks

this video is brought to you by athletic 

turn into long-running inside jokes that 

to this universal problem all you'd have 

crawl and jump from building to building 

you were spider-man you'd always be able 

out without you and you'd be able to get 

which is the goal right science has done 

here we simply think it's high time that 

and turn us into a spider person is that 

but before we get into it i want to tell 

days when i don't have the energy to hit 

the gym or make a gigantic salad ag-1 by 

nutritional needs and it supports my gut 

health energy and focus too and athletic 

supply of vitamin d and five free travel 

couldn't be easier to prepare all i need 

include dairy free probiotics adaptogens 

antioxidants and digestive enzymes don't
