I wonder if modern rates of depression are normal, and we're just diagnosing cases more accurately, or if more people are becoming depressives. I haven't got data, and I'm not an expert in this field, but it feels to me like the latter is what's happening. If this is the case, I wonder what is causing it, and how it can be remediated. I don't remember so many people being depressed when I was young.
