Ipods have been found to interfere with pacemakers. So, unless you're trying to give the elderly a heart attack, you should prolly keep it away from them. Hopefully, by the time we're using pacemakers, they'll have solved this problem. Course, we might have run out of power to keep any of it running. Or we could die from cancer and never make it to the point where we might need a pacemaker. You gotta think positively.

Cell phones also interfere with pacemakers, but mobile phone manufacturers tell users that it's not a big deal. Just don't put it in a shirt pocket. Cause mobile phone manufactuers would be the first people to dissuade the use of cell phones if they thought it might cause harm. Riiight.
