Cranky? You may be smarter than you think

Being cranky when you’re young may not be so bad. A study found that people who were cranky in their youth were smarter in their senior years compared to their more easy-going counterparts. It’s not clear though whether being cranky makes one smarter or being smarter makes one cranky. In any case, the easy-going folks may actually be the smart ones if they end up enjoying their golden years more.
