> I was a D1 scholarship athlete and there was no way I was telling anyone when I got a concussion in high school after they made it clear what the risks were, including field removal.

For clarification, I don't know anything about US and American Football, you did not tell because it would have hindered your career or you made a typo here and you meant you would definitely because of the health risks?

When did your neuro issues first appear and how?

Yeah, I didn't think it had to do with geological activity, because it looks like they're also observing this phenomenon on the East Coast and the Gulf of Mexico, which I don't think are known for having seismic activity.

What a depressing thing to know. I play soccer, and I love playing it, I don't practice heading, but I just play as hobby and sure in some cases I have to head the ball. It always felt nasty, but I thought surely it's safe or otherwise soccer wouldn't be as popular sport as it is.

Now I'm not sure if I should quit or simply never head the ball... I always look forward to playing and can't wait to play.

Maybe at least in training I will stop heading any faster moving balls. From now on though whenever I head the ball I'm left wondering how many IQ points did I exactly lose this time. Was it 0.01 or 0.001? 100 or 1000 headings would yield in drop of 1 IQ point.

I would like to see a study where it compares IQs (and other mental performance test results) at certain age for soccer players and IQ for same players in 10 years or different various time periods. For all pro, amateur, sunday league.

There's not a single interpretation of "preventing a consequence of evolution" that is factually correct. You do seem to believe and imply that avoiding death prevents evolution. I'm not really sure what you think "consequences of evolution" are, but death is no more a consequence than living, breeding or having a drink by the beach are evolutionary consequences.

I also have a 3 year-old. If she wakes up to pee I’m screwed because I can’t go back to sleep. Between a full-time job and being a dad I overindulge in my hobbies when the time is available. I’ve had a sleeping problem since I was a teenager. I guess this messes up my plans for living to be 99 like my grandfather.

>Evolution isn't merely about dying.

Please highlight where I said this.

>Evolution is here, alive and well.

Or where I claimed evolution is something that isn't happening.

Like I said, you should have spent more time reading/thinking before replying.

You can already get strains that are really high in THC, CBG and CBD.

Dude your comment is so utterly ignorant, you should maybe have a few days to read about what evolution is before writing.

Evolution isn't merely about dying. Yes it's a big part of it, and I did call it "crucial" too, but there's so much more to the process, it isn't even the biggest part. Number one, it's about spreading genes. Procreation is even more important than survival and leads to evolution on its own. Stopping death doesn't stop evolution by any means...

Secondly none of the cases you listed are examples of beating or preventing evolution or anything. They are just examples of a species dealing with problems in its own way.

You don't think beavers building dams or termites building a mound to avoid dying from floods is them cheating evolution, do you? Just because you make things to avoid dying doesn't mean you're avoiding evolution. Quite the contrary, you're fulfilling it. Your beneficial traits allowed you to survive where you otherwise wouldn't have and henceforth the living world will be more filled with the genes providing these beneficial traits. Smartness, culture and transfer of knowledge, as exemplified by humans, are clearly successful traits and they have lead to us becoming the most dominant mammal on Earth. To the point that humans and the species we use for food make up the weight of 90% of all mammal biomass... That's evolution in action.

And when some unfortunate person in Brazil or India or the US can't be saved by a coronary artery bypass because it isn't free and they were born too dumb to have a nice job and afford it, or too sickly to keep up with all their disases or too asocial to have a nice support network; then that would be evolution too. But the far more common type of evolution in the 21st century would be when some human beings are having more kids raised to adulthood than others. Evolution is here, alive and well.

Does it work in the same way as a checkpoint inhibitor?

Its kinda like how some people wear teeth guards or crotch cuts then right?

Edit: If anything it would create a better focal point for head butting the ball and could cause even more damage on second thought.

You deny that we are able to overcome any of the restrictions evolution has imposed on us? So any time a child is born premature and survives due to modern medicine, when they would have died otherwise, that is what exactly? Any time someone with a genetic predisposition to cardiovascular disease is saved with at coronary artery bypass, what are we doing if we are not preventing a consequence of evolution?

Maybe try having a few days think before replying this time.

I remember hearing / reading about these warmer temperatures off the Oregon coast a while back. They alluded to it being a problem then.

I am telling you all along, its the aliens ! And nobody is listening, they are mining our earth core because they hid something in there billions of years ago. We should stop them now or it will be too late when they get to it. What do you think are doing those heatwaves under ocean ? Its alien deep sea laser mining drills !

[mTBI = mild traumatic brain injury i.e., concussion]

Won’t make too much of a difference, I imagine.

You can receive a mTBI from a hit to the chest. No direct contact to the head is even required.

Think of the brain like an egg. You can scramble and egg in its shell if you shake it hard enough back and forth. No need to “hit” the shell at all.

Another similar example is why soldiers can receive concussions from explosions without hitting their heads.

mTBI’s can (mostly) be mitigated by neck stabilization, but that comes with it’s own issues and impracticalities — won’t work in most sports really.

However, the brain cannot be completely stabilized inside the skull. So, mTBI’s cannot be 100% avoided regardless of the equipment used.

My comment was tongue in cheek about the all knowing redditors who critiquing published science. As if they were the equivalent of a journal reviewer/editor. Especially criticizing something like proper experimental controls, as if the reviewers didn’t notice - it’s arrogant/ignorant to the process

The brain is plastic, use it or lose it
