SUNSCREEN in UV

Honest education is priceless, and what you guys provide is for the greater good, love that, and your work! Although, what I feel that wasn't discussed here (in a more important note), was the fact that humans have been on this planet for millions of years, and "cancer" hasn't been a problem until modern medicine. More specifically to the topic of your video (cause we all know there are multiple versions of cancer) and how we need to be "worried" (now) about being exposed to the sun, when we should understand that our ancestors were exposed to it in an exponential amount more than us.

I get this is a broad topic and you guys are focused on physics rather than medicine, and you two are fairly big players in the Influencer realm of the physics arena. Although, in my opinion, I believe in order to make real progress we should collaborate with other areas of scientific study (in a 'everyone/public' setting like this) so that we can uncover the unjust healthcare and education system (yes, that's loaded .. ) that put us in the position of fearing something that was created by our current system (yup .. even more loaded :) ) Love you both!
