Darkness on the Edge of Downtown
I kind of mentioned it a week or so ago, and it is now here. Even after I get up at 6 a.m. and shower, the sun has not yet risen.
Indeed, the sky is now only starting to surrender its almost black hue to purple, and there is no dramatic color in the sky as I write this post. Sadly, it is that time, light and weather wise.

Cheer up - in a few more weeks the days start getting longer :)
A simple water treatment process called SODIS (solar water disinfection) consists of filling polluted water in PET bottles that are exposed to sunlight for 5–6 hours. However, sunlight does not only destroy disease-causing microorganisms found in the water but also transforms the plastic material into photoproducts. Laboratory and field tests revealed that these photoproducts are generated at the outer surface of the bottles. No indication for migration of possible photoproducts or additives from PET bottles into water was observed with the applied analytical methods.
The same our visualization and the earth surface as well. Human eye is like a car light, it causes to weaken if not used properly.
