A few months ago one of my coworkers collapsed at work. We got him transported to the hospital and didn't know what happened. Unfortunately he was told it was brain cancer specifically Glioblastoma a very deadly brain cancer that is difficult to treat. Surgery was performed to get most of the tumor out but there were parts that just could not be addressed.
He was able to return to work and is now wearing one of these units:
This thing blew my mind so I began reading about it. Here's an excellent TED talk on how it works:
The research and technology that goes into something like this amazes me. My coworker is a maintenance tech and is pretty much able to do everything he did before just now wearing the headgear and humping around something that weighs about the same as a laptop. The biggest issue he's talked about is the way the unit is setup in the backpack the battery is against his back. We put some bubble wrap in what I called the Camelbak space on the backpack (for spare batteries) and that provided a bit of insulation so his back didn't get so hot.
This is a great guy who I pray this treatment is as effective as they say it is. This guy went to the mall and was walking around with this unit on in a bookstore picking up books and then setting them down saying "boy, that was a good read" just messing with people.
Cancer sucks but that means you can't have fun kicking its ass.
