A new study said older applicants for certain jobs demonstrate more intelligence.

The study in the Journal of Applied Psychology looked at 3,000 people ages 20 to 74 applying to executive level jobs and found essentially gray hair matters.

Downtown Phoenix' Tommy Pastrami owner Len Combs takes pride in what his workers, of all ages, cook up.

"The oldest employees are pushing 60 and the youngest are 18," Combs said.

While the study didn't particularly apply to Combs line of work, he said he takes seriously what it found -- that those gray-haired employees are more than worth it to hire.

"They're not nervous, they're open and have a lot of lifetime experiences they can share and that really carries through in a conversation," Combs said.

The study says under that head of silver, there's higher "crystallized intelligence," for example they can communicate better.

Career coach Michael Seaver said when it comes to baby boomers concerns seeking out those complex or highly specialized skilled positions.

"I'm not seeing quite as much worry or concern," he said.

There are some disadvantages to older workers. Combs said they have less technical skills and concern of using a computer. The study said the older workers have less of an ability to reason particularly after age 59.

"But the most successful organizations are the one that have very, very diverse talent," Seaver said. He said that can come in life experiences and background.

So that saying out with the old and in with the new, might not ring so true after all.
