Depression is a bit of catch-all term. Considering that some forms are immune to certain drugs, but not the other, or that for some kinds therapy works better (or worse) - it is very likely that when we learn more about depression, we will type it like diabetes (depression type 1, type 2 etc).
Thus it is theoretically possible that there is a type of what we currently call depression that can get better with mental effort.
I personally haven’t seen it, but I also haven’t seen Thailand and it still exists :-)




I am familiar with the research. We don’t know the reason for nearsightedness. There is no known proven causation. It is likely there are different causes for it.
Being from a sunny country lowers the chance of it (so you’re less likely to be nearsighted if you’re from Spain compared to Norway), even when controlled for hours spent outdoors.
