Noncancerous tumors. Noncancerous tumors may develop in the ear canal, blocking it and causing hearing loss and a buildup of earwax. Exostoses occur in people who swim in cold water, such as scuba divers and surfers. Surfer's ear is a common term for bony exostosis in the ear canal. The most effective treatment for these noncancerous bony tumors is surgical removal. After treatment, hearing usually returns to normal.
No, a bar of gold (like the ones at Fort Knox) weights roughly 400 troy ounces, or about 27.5 pounds.
There is no 'standard' bar of gold. Bars come in a range of weights, starting from 1 gram to 1000 grams generally. I have handled the following bars: 1 gram, 2 grams, 5 grams, 10 grams, 11.664 grams (1 tola).
