Are you an addict too?

Started a new Coursera class today, “The Addicted Brain”.  The instructor, prof Michael Kuhar, defines “addiction”  as “repeated behavior that results in distress or has a negative impact.” Among the “addictive” substances we’ll explore is caffeine (aka, “Starbucks!) .  Does caffeine cause distress or have a negative impact in your life? http://go.shr.lc/TJ8X1s
