People do tend to be happier and carry less stress in the summer. My vote would be that their outside time increases, thereby decreasing stress. For me that always works. Anyone else notice that?
One encouraging thing to note this summer is the amount of people going old school with one particular thing - gardens, specifically vegetable gardens. Whether the gardens are raised bed, vertical, hydro - or aquaponic or container gardens, it is a good sign to see more and more people trying to get a handle on where their food is coming from. In light of the many chemical additives and genetic changes to our food, this is the best line of self defence for your health. I say, "old school" because most people used to have a small garden, two generations ago. Sure it was because of war rations or at least in part because of it, but it made good sense.
Supermarkets, as we know them, made their appearance in the late 1940's and as people got used to having food readily available at reasonable prices, it was easy to hang up the garden gloves.
In the same way that cheap hydro power convinced the farmers to give up their independence due to their own wind generators, the supermarket weaned people away from the control of what goes on/into their food and how long it is kept.
Flash forward to 2016... we have GMO's which are not labelled and have no long term testing to know how they will affect this, never mind the next generation, we have wheat being sprayed with glyphosate (a chemical which passes the blood/brain barrier and can not be washed off), we have high fructose corn syrup (otherwise used as ethanol, which is a poison to your liver) being masked under a variety of names in many products, and so many pre-packaged foods with a variety of dangerous additives. So, yes, I have a garden and yes, I purposely bought a small acreage with a view to making myself more sustainable. I think that if you are blindly trusting the food companies and the government to do for you what you should be doing for yourself, namely putting at least some of your food on your own table, then you can expect some health problems. Not that I wish it on anyone...
I would encourage anyone and everyone to at least do a container garden or a intertior bottle garden this fall/winter if you missed the summer. I have plans along those lines also. But beware!
Eating fresh food from your own gardening and getting down and dirty raising that food is habit forming and give you a great feeling of contentment. (Never mind how it helps your health!)
Enjoy your summer!
