Don't go by the shutter activations as shown - I'm about to roll my counter a second time now and could easily claim it has just a few activations.
Might want to check the serial number with Pentax, perhaps they registered it and you can get an idea on date of purchase.
Check the camera for any faults now - shoot away, RAW as Ben suggested, pixel peep a few of your images (examine the image closely for any problems not caused by human error), look for stress fractures on the tripod or camera strap mounts, check for dust on your sensor, examine the flash hot-shoe for any damage or loseness, inspect everything!
