Oil deterioration at low temp.

Now we got into winter season in Japan and the temperature outside became lower than zero centigrade.
Following the circumstantial change, the physical property of materials changes also especially the viscosity of oils in a car.  As the brake fluid is not made from mineral one but from vegetable one, deterioration and degeneration of liquid material sometime causes clogging in a mechanical constructions, among them operative brake cylinder inside is not be ignored at all.
My VW Super Beetle has drum designed brake systems on 4 wheels, 5 years interval  from the latest maintenance needs periodical checking if the systems keep working, a possibility of one hand operation would be doubted, leading side or trailing side.
I'm going to proceed to a muscle working on the break system maintenance today, but it's relatively convenient for me to do that because the temperature is low and I need some athletic training these days.

Wondering in the Web site this morning, I happened to come across an interesting lecture about Emotional Condition, the comparison between the ancient nomad people lasted for 10,000,000 years till the agricultural race appeared and the settlement ethnicity, lasting for 10,000 years. The influence in people's mind caused by the Settlement Restraint is very impressive and moved me so much and I would like to dig this title a bit more.
