Interesting story, via yoyogurl:

He’s 57 years old, afflicted with skin cancer, partially deaf and suffers from high blood pressure. But the U.S. Army still wants Master Sgt. Luis Jaime Treviño.

On July 14, the Vietnam and Desert Storm veteran received his third order to report to active duty — mobilized for Operation Iraqi Freedom.

"I was very shocked," Treviño said, a member of the Army’s Individual Ready Reserve. IRRs are not part of a reserve unit, do not get paid and do not attend monthly reserve training. However, because of critical skills they possess, they can be recalled to duty if needed.

In disbelief, he called the Army hotline listed on his orders.

"Am I reading this thing right? At my age you still want me?" he asked.

But there was no mistake. Treviño is to report to a mobilization unit Sept. 15 at Fort Jackson, S.C. "If I do not execute these orders, I go to jail," he said.
...
Reservists under the age of 60 are being activated, said Public Affairs Specialist Julia Collins of the Human Resources Command in St. Louis.

"I know many guys who are in that position," she said. "It’s not unusual."

While Treviño’s age does not disqualify him from serving, his medical condition may.

The U.S. Veteran’s Administration considers Treviño 100 percent disabled because of the cancerous cells on his face and his bilateral hearing loss.

His middle left finger is bandaged, hiding the portion doctors removed on Thursday for a biopsy. He also takes medicine daily to control his blood pressure and hypertension.

"Treviño is a refueling specialist, an expert in petroleum, oils and lubricants."
