What do young, single guys hardly ever do? Is it pay for everything on a date? Call the next day after first having sex with a girl? Ask a woman's father for permission to marry his daughter? Sheets. They hardly ever change their bedsheets.

According to MSN, a survey by UK mattress company Ergoflex reveals,

The average single man changes his bed sheets just once every three months and owns just one set of bed linen. A new survey has revealed that 55% of men between 18 and 25 wash their sheets just four times a year.

Single women came out of the survey of 2,004 people by mattress maker Ergoflex, smelling of roses, claiming to change their bed sheets once every two and a half weeks. Couples appeared the cleanest, changing their sheets every two weeks.

When the men were asked about their lack of hygiene, 19% did not care.
