In the previous post in this series, the index of satisfaction (IS = optimism / happiness) had stabilized for a change. However, the most recent data clearly demonstrate that the long term trends are fraught with uncertainty.
A sharp drop followed by a gradual recovery was nobody's guess. And once again, we don't know if it's optimism that's going thru a turbulent period or happiness is fluctuating depending on the amount of wine intake.
I will continue to monitor this crucial index and provide updates.
