Take hits to the head seriously

The president of the US knocked NFL on rules: ‘Concussions — ‘Uh oh, got a little ding on the head?' in 2016, and calling the rules “soft”.
While he's wrong, he's not alone in thinking that way. The reason for that is that if someone hasn't had an injury, or knows someone who has, they don't understand.
While concussions are sometimes invisible to the eye, the effects aren't.
I've got plenty of challenges, of that there's no doubt, but the fact that I'm visibly-disabled is a plus. Why? Because if I stop for a few seconds, and do something that isn't simply moving forward, someone usually stops, and asks me if I'd like some help.
What I don't understand is that some doctors consider traumatic brain injury and concussion as two separate diagnostic categories, when in truth, both reflect brain injury.
When people go to the hospital, after getting hit on the head, what's weird (wrong) is that concussion is sometimes termed, over "brain injury." The reason for that is strongly associated with earlier discharge from the hospital and earlier return to school activities, the researchers say.
But, with the reality that they're the same, and post-crash effects can appear later, researchers recommend that more specific descriptions of concussion and brain injury should be used. The reason for that is that a more detailed explanation can include elements that would warn of the potential occurrences of issues.
Using the term “mild traumatic brain injury” rather than “concussion” might help people better understand what they are dealing with and improve decisions about what the children should be allowed to do.

Visionary – Steve Jobs and now Elon Musk

This entry doesn't immediately seem to fit into this blog, because what it's about doesn't immediately fit with what this story is about. But, it is. Why? Because what I'm about is the minimizing the differences between myself, and someone who hasn't suffered an injury that's rendered them unable to drive. Put it this way, with what Elon is thinking, while the notion of my being able get into a Tesla is highly-unlikely (simply because of cost), the concept of taking one alone is impossible. However, with what he's proposing, not only will riding in one be possible, but doing so alone.
Teslas, are cooler than pretty much anything, of that there's no doubt, but they're not cheap! But, as with everything, while the price starts high, as skills/production/everything else improves, the cost to make will reduce.
Visionaries don't see the cost of making things, nor do they worry about "little things" that would get in the way, because all they see is the result.
Everything that's designed follows a 3-step process of questions, which is "what do we need?", followed by "how do we do it". At the centre is why it's being thought of. Nearly every invention follows the process, starting at the outside, and working in. Steve Jobs, who invented the Mac computers, followed it, but reversed the order. He thought of why what he's inventing is needed. He solved it, and worked out.
Elon Musk is a visionary, of that there's no doubt, because he's making going to space more of a common-thing, and now he's announced that he'll be into making self-driving taxis.
I'm looking at my computer, the where I store my info for backup, and this will show more of what I just said.
Everything that's somewhat standard now was "holy cow, that's awesome!!" when it was first launched, and cost a fortune. In a long time, cars like this will likely simply be "just a car", and the fact that it's driverless, and a taxi, won't be anything weird.
