Birthday in May? Then you're right to think you were born lucky

I was born in May. I look at when animals have their young and it's in the spring. If it's good enough for them it's good enough for me.
"There are people who believe they were born lucky. And some who believe they were not. And the difference between them, according to new research, is about six months. If your birthday is in May you are probably one of the lucky people, whereas November babies tend to get a raw deal, psychologists say."
