A spokesman for online market researchers OnePoll, which commissioned the research, said: "Women are often said to be the more complicated sex, but it seems men still have their unexplainable traits.

"Men and women are often very different - in the way they behave, communicate, express their emotions and deal with problems. But this can leave women struggling to understand why men do certain things.

"Man flu in particular is always a bone of contention, especially for couples. While women are known to struggle on while suffering a cold, men always seem to come down with a stronger bug that knocks them for six."
