She said that despite his declining health, he's still doing all he can to help his family. 'Even on his death bed, he's making plans,' she said.

The call to action is simple: The family is asking everyone to pick up a birthday card and mail it in time for the April 11 celebration with whatever message comes to heart.

'Thanking him for his service, celebrating this milestone... There's nothing specific we're requesting people to say. I think people already know what to say,' Medina said.

Getting 100 birthday cards honoring the incredible life of a local war hero doesn't seem like enough. Through the global reach of social media, the family may need to enlist an army to surprise Dumlao with the truckloads of thank you notes he so deserves.

Birthday cards can be mailed to: Justo Dumlao, PO Box 2178, Universal City, TX 78148.
