A new public service announcement takes a lighthearted look at men and their apparent reluctance to get a check-up. But, in real life, the situation is serious. It's estimated that men are 25% less likely to visit a doctor than women.   

"To a large extent, I think there is just a lot of denial going on and in some cases that denial can be deadly," said Dr. Allen Dollar. 

That was almost the case for Bill Horrisberger. He ignored chest pains for more than a month. 

"I didn't feel that bad," said Horrisberger. 

It was his long-time girlfriend who encouraged him to get a check-up. 

"Once he got started, once he realized what was at stake, he was a good patient," said Judy Kelly, his girlfriend.

Dr. Dollar says he's heard just about every excuse from male patients. He believes some men are just afraid of doctors and may try to be macho about it.

"Testosterone leads to feelings of invincibility and immortality," said Dr. Dollar.
