Those in a serious relationship have long been warned about the dangers of the seven-year itch¹. But research has found couples risk running into trouble far earlier - thanks to the seven-month slouch.

已婚男女要警惕“七年之痒”说法由来已久。但一项调查发现，情侣之间出现问题的时间要远远早于七年，这就是“七月之懒”。

Seven Year Itch: Marilyn Monroe's 1955 film of the same name told of the perils for couples.

This is the point at which we stop trying quite so hard to impress our new love and start revealing all the bad habits that have so far remained hidden.

These can include unsavoury（令人讨厌的） bodily functions such as breaking wind（放屁） in front of an other half, nose picking or letting armpits（腋窝） go unshaven. Before the milestone³, most couples enjoy an extended honeymoon⁴ period where both go out of their way to keep well-groomed and observe good manners.

However, it seems once a couple has been together for around seven months they decide they really do love each other and start to let go.

According to a survey of 1,000 adults, the seven-month point is when couples are most likely to think it acceptable to stop paying attention to details such as shaving regularly and keeping nails trimmed while also putting their bad habits on display.

More than nine in ten women and almost as many men admit that they let themselves go once they are in the full throes（剧痛，痛苦的挣扎） of a romance.

However it seems men are far happier to relax their standards while more women told researchers from Remington that they never allow themselves to be seen looking hairy（多毛的，毛状的） or too unkempt（蓬乱的，不整洁的） .

More than half of all adults said they make a special effort at the start of a relationship.

Once life with their other half becomes more routine, 48 percent said they start breaking wind in front of their partner, 68 percent will skip sexy clothes for unflattering（准确无误的，坦率的） outfits⁵（装备） round the house and 58 percent walk around naked.

Only 6 percent said they would never let their partner see them be so uncouth⁶（笨拙的，粗野的） .

There are also still some traditionalists out there, with 13 percent saying they believe revealing bad habits is only acceptable after marriage.
