Finishing other people’s sentences, cracking your knuckles and biting your toenails all feature in a chart of Brits’ worst habits.
More than 90 per cent admit to having at least one bad habit, with one in ten admitting to ten or more weaknesses.
Swearing was the most common trait, followed by nose-picking, not listening when others are speaking and biting your nails.
Over-using social media, hoarding and not washing your hands after going to the toilet also feature in the top 50.
But the study of 2,000 UK adults, by ColdZyme Mouth Spray, revealed that one in 10 has suffered a cold or stomach bug due to a bad habit.
A fifth of people surveyed admitted they had actually fallen out with a friend or loved one over a vice.
A spokesperson for ColdZyme Mouth Spray said: “Almost everyone will have at least one bad habit at some point whether it’s checking in on social media a little too often or indulging in a type of food you shouldn’t.
“But while many bad habits will be virtually harmless, some can be pretty annoying to other people, while others can have a serious effect on your health.
“Something as seemingly insignificant as not washing your hands or biting your nails often can lead to a cold or bug, or even pass your germs on to an unsuspecting stranger or loved one.”
