Something interesting to probably no one but me.
This was taken from one of my favorite design sites, core77.com :
"...a new study by researchers [tested] to see if there was any connection between physical and emotional heat.
To their surprise, they found that people who held a cup of hot coffee for 10 to 25 seconds warmed to a perfect stranger. Holding a cup of iced coffee had the opposite effect."
Maybe this is why coffee shops have that laid back, just like home, sort of feel to them. I guess next time you're feeling stressed out. Take the time to hug a warm cup of coffee or tea with your hands, it'll calm you down some.
