Fuck... rest in peace to an incredibly bright and talented man. We grew up on Mythbusters and I just happened to look him up the other day to see what the crew has been up to.
Brain aneurysms are beyond scary; my fiancee's aunt had one burst around 5 years ago just as she parked at the grocery store. She came to a few minutes later, and actually drove herself to the hospital ER down the street. By an extreme stroke of luck and timeliness, she survived, but my goodness the events were razor thin. She just so happened to drive herself, if she called for an ambulance and waited she wouldn't have made it. She stumbled into the ER and the nurse just so happened to acknowledge there was some brain trauma occurring and immediately rushed her in. She also just so happened to have it when one of the top neurosurgeons in the country was present at the hospital, and was able to jump right in to surgery. She barely survived.
She got another scan this past fall and they discovered 2 new aneurysms had developed. They decided to opt for preventative surgery to take care of them before they ruptured, but she almost didn't make it then either. Recovery was very long, but she's now back to her normal self. Life is beautiful and scary at the same time, things like this really make you perceive mortality in new ways.
