Basically all people except for a select few do.
Our minds shape themselves most of all when we are young, the younger we are the more this happens. This is why kids are so flexible when it comes to changes, since for them everything is new anyway, and they got to absorb it all if they are to use it when they are adults.
The older we get the more our brain will reject learning new things. Some people are still willing to push through this, and try to accept things change, and other people don't want to do that from the beginning. The days in which our lives began will therefore always shape the template of what we become later. But the world changes faster than people who are 'too old' to accept new changes die out, and as a result they feel out of place and try to get back to their comfort zone, which is the world the way it used to be. And some old people do try to accept the changes the world underwent, but will still have trouble doing so, but as long as you are willing to be open-minded, you can sometimes get quite far anyway.
But in the end kids are meant to learn everything the way it is, and old people are not as they are supposed to know already and use that what they always knew, that is the will of nature, however since humans don't live by the rules of nature anymore and times chances quickly (which doesn't happen in the wild), nature gets a bit busted, and I guess older people pay the price.
Now it's not that old people don't learn at all. There are many things you can only learn by living for a long time. It's for a reason after all that in many cultures old people are considered wise.
