playing with lots of mercury when i was a kid

Hello. When i was a kid in the 60;s i used to play with mercury all the time, and when i say all the time for about a summer, i did. and, it wasn't a little bit, either it was a whopping 5-6 oz blob of it. My brother(9 years older). stole it from his chemistry lab a high school. and, i used to snoop through his desk drawers and i found it. it was so much fun to play with, drop it and it bounced into little silver balls, scoop it back up, wobble it around in the palm of my hands.
Now, my question is this, how much of the stuff got into my system via my skin pores? I was told one time that the mercury molecule is too big to penetrate the tiny pores of the skin. so, i'm hoping i didn't do too much damage to myself. does anyone know if this is true? could an expert in Mercury please advise. thankyou.
