This is a special mini episode that I hope you really enjoy.

I retired the cool fact of the day from Bulletproof Radio after about 700 episodes,

and I miss it. And some listeners just were skipping through it, and I don't want to waste your time.

But as soon as I turned it off, a whole bunch of people said,

Dave, what's going on? I missed this. So if you're one of those people who likes quick,

funny, and interesting little tidbits, I put together just a short episode for you here.

So this is something I'll do on occasion for you when there's just cool stuff that's worth talking about.

So once a month on Fridays, the cool stuff is still happening.

And if you subscribe to Bulletproof Radio on your favorite podcast platform,

you'll get all the other cool knowledge and all the episodes.

I've been getting more of the legends, more of the masters, people who've spent decades

in their fields, toiling largely in obscurity, who are now bringing crazy levels of knowledge out here.

I've never felt like I'm learning as much as I am now, but I'm still going to do cool facts for you

because hey, I'm a dark enjoy.

This cool fact is about EMF exposure in kids' brains.

It's also been a new study, surprise scientists.

The Barcelona Institute for Global Health studied about 2500 Dutch kids in ages 9-12 to find out

if mobile devices affected their brain volume. You're not going to like this one.

They explored the relationship between brain volume and different doses of radio frequency electromagnetic fields.

Well, they did not find associations between alterations in total or low specific brain volume

and overall radio frequencies or electromagnetic frequency doses.

They didn't find any associations between brain volume and the use of mobile devices for making calls either.
