It wasn't only the transportation industry that grasped aluminium's advantages. By the early 1900s, aluminium had already supplanted copper in electrical power lines, its flexibility, light weight and low cost more than compensating for its poorer conductivity.

Swallowing over-the-counter antacids can raise intake levels by several thousand-fold. And many of us apply aluminium-containing deodorants directly to our skin every day. What's worrying about all this is that several studies have implicated aluminium as a riziko factor for both breast cancer and Alzheimer's disease.
