Remember that time Steve Jobs, countering Zune sharing, offered that the only way to share music was to intimately place one of your earbuds into another's ear? Well that's a bad idea, bacteria-wise.
According to a recent study by India's Manipal University, users who shared earbuds were found to house harmful bacteria in their ears in 93% of test swabs. Meanwhile, those (prudes) who didn't share earbuds were found to house harmful bacteria in their ears just 8% of the time.
Of course, there could be some other correlations going on that artificially skew the data. Like those who shared earphones were also more likely to share their ears with tongues, piercings and romantic earwax candles. Wait...maybe this sharing earbuds lifestyle isn't so bad after all.
