Odds of battery just dying?

Had a 97 pickup as my daily driver, never had a problem! Drove it to work one snowy day and met the plow truck coming down the hill, I was going up! I pulled into a driveway so he could go by, backed out and started up the hill and stalled it, manual trans! Started it up, no problem, stalled again! Go to start it again.....dead! Just like that, the battery went, and I mean went! A lady in a Cadillac got me jump started, made it to the job, push started it to get home, tested the battery.....dead!!!

As the great philosopher and thinker of thoughts Forrest Gump once said...."it happens"!!!
