I remember seeing the bit about the 60th percentile before. That is NOT high silver, that is just 10 percentile points above average if the 50th percentile is the average (which it almost always is). That means that 40 percent of the population tested have higher levels than you do. So you are below average in mercury and tin and only a little above average in silver, lead and arsenic. Even nickel is not highly elevated - 28% of the population tested has higher levels.
