No. No matter what I've accomplished in my life or places I've visited, nothing has helped me get better at X if I wasn't doing X. I'm most certainly wiser than I was 20 years ago, but that doesn't mean I learned extra skills by osmosis. And since PCs get ASIs as they level up, they do get better than level 1 PCs in general. Whatever the player decides to put those ASIs into.So you all don’t believe that the level 20 adventurer tends to be naturally more perceptive than the level 1?
That the level 20 fighter hasn’t gotten a little smarter in his adventures (defining smart as more knowledge)
*edit* If I were to use myself as an example how I've "leveled up" since I was younger in D&D terms, it seems my ASIs went into intelligence and wisdom, and not strength or anything else. So I am better at general things than my level 1 self back in the day for things relating to intelligence or wisdom. You can do the exact same thing with PCs. A level 20 PC who put ASIs into intelligence and wisdom would have a better chance at things like perception or investigation than the level 1 counterpart. they don't need an extra prof bonus to be added to that to be better. And if they never did task X, there is no reason why they should be better
