My mum once attempted to explain the circulatory system to me, including the bit about valves that only open one way when the pressure of the blood behind them hits a certain level (or something). I got the impression that this happened because you were moving about and that if you ever stopped moving the valves wouldn't work, the blood would pool in one limb in your body and eventually that bit would die. I blame my inability to sit still on that bit of badly explained science.

My Dad told me that if I didn't let him get splinters out, they'd travel up to my heart and I'd die... Thet's not true is it?

My mother told me that you only had a certain amount of breaths in your life, this was so I didn't talk to much. This made me believe that athletes would die really young because of all the heavy breathing they did.

I believed that if you held your breath, then your heart would stop during the time that you were holding your breath ... and start again when you started breathing.
