Hey @Stellabelle!
Thank you for issuing a challenge for a humble, yet noble cause -- to change the world! I sure hope to see you in Lisbon!! (I’ll even reserve a jet-lag buster just for you.)
Go easy on me -- this Steemfest entry is my VERY FIRST VIDEO:
Health Power to the People
Hi! 
I'm super-stoked about my most recent discovery - it’s a perfect blend of technology and natural healing. It’s so great! I use it every day.
What is it?
Red light therapy. A special blend of color, light and quantum healing codes. Simple. Safe. Easy. Effective.
What’s the REDjuvenatorTM done for me?:
Well, I look 10 years younger. I have a lot more energy. And OMG, I sleep so much deeper.
Check it out online — you'll find tons of testimonials for tons of different health conditions.
I bought several RejuvenatorTM panels to “spread the health.” But, they aren't cheap. So, I lent them to my friends and family.
And Wow! They love light therapy. It’s been amazing for them.
My "local lending" has sparked a broader vision for me.
A world-changing vision.
Imagine…a global lending network of wellness products. No need to “buy” big ticket items, just “rent and try!”
No bureaucracy. No insurance companies. No prescription drugs. Just health power to the people.
This global lending network of wellness products will disrupt bloated, dysfunctional health care systems. It's open. It’s decentralized. It’s accessible. — Just like cryptocurrency!
The first product in the lending network will be the REDjuvenatorTM.
And the engine behind the network?
