I'm of the opinion that calm canal life, or at least a spell of it, can help some who are suffering from the astounding and shocking effects of the chemical inbalance that stress and anxiety can cause in the body and the old noggin.
Also, it might be worth bearing in mind that in this modern life we now lead , many man made chemicals are getting into our bodies that really shouldn't be in the same room as us.
As well as huge doses, minute amounts of nasty chemicals can have some very disturbing physical and mind altering effects on peeps..... including the boaters dreaded enemy - carbon monoxide!
For many of those who are suffering from some forms of mental health hiccups - take heart, you're not a nutcase ....it / you can often be made better. It can just sometimes take time, with the help of experts - and understanding family and friends, in getting your/the 'chemical mix' back to normal tickover mode.
