Found this extract from an article written by Dr. Joel Kahn, completely unknown to me, but thought it is interesting...
"...........a published study of patients with clogged heart arteries due to atherosclerosis. Over 100 of these patients had an EKG performed while a cell phone in the off position was placed at their waist and then over their heart. Then the EKG was repeated while the phone rang for 40 seconds at the same positions. Turns out that the cell phone ring caused higher QT levels, which is associated with heart rhythm problems. "
We do have a member who is certain his phone kept in his breast pocket affected his heart rhythm.
It goes on to say that keeping your phone in your pocket, like I do, near your "private" parts may not be a good idea either.
He says distance is everything, so in a handbag is good. Not sure what guys can do except a man-bag? Looked at protective cases but it reads as though you then can't receive calls, not sure?
