FORTUNE — To mark the iPhone’s fifth birthday on June 29, Gazelle — a service that buys used Apple (AAPL) devices at steep discounts — took a survey of more than 1,000 customers and made several disturbing discoveries. From the press release:

• Asked which device or platform they would not be able to live without, a majority (65%) chose iPhone, while only a few (1%) report not being able to do without Facebook.
• Nearly 15% of respondents said they’d rather give up sex than go for even a weekend without their iPhone. (Emphasis ours.)
• More than 25% of survey respondents report that they “almost always” use their iPhone while in a social setting such as during a meal or while at a party.
• Nearly 4% of respondents report having used their iPhone while having sex. (Emphasis ours.)
• Nearly 85% of respondents report having used their iPhone while in the bathroom.

Too much information.
