The point is simply to realize that some of the things our culture values are not that important.
By whose standards ? Yours? Mine? The Government? Who decides? Sounds too much like censorship to me. Let anarchy reign and let's just try and make the best of it.
To simply say that all mental health is directly related to genes and not our everyday situations is simplistic. Lifestyle plays a very important role in our mental health
This is true of course. But there has always been mental illness, always, since we first crawled out of the swamp. Cats and dogs can have mental illnesses, and you're not telling me that's because they watch too much TV? (Although that may be the case in some countries

). It's not Playstations and Beefburgers, the hole in the ozone layer, glogal warning, religion, atheism, air-conditioning etc, etc, that is screwing us up - they are just different flavours of detrimental factors that have always been around to torment us.
The fact that we have the
capacity for mental illness is the problem. And we can't do anything about that, so we are buggered for eternity. No amount of simple living with stave off the inevitable. But we
can choose to live our lives in a way that gives us peace of mind, at the very least. Yet the longer we lay about thinking about it, or moaning about the ills of the world, the less time we have to act on it. Get up, get out, get laid, get drunk, plant a tree, adopt a whale....do....something.
