It was discovered by 15 year old GCSE students in Brighton today that the main cause for erectile dysfunction in men aged 20-65 is...ugly women.
They came to the conclusion that if women took care of themselves a bit better instead of complaining that their partner can't get it up, that relationships would be better.
Dr. Thaksin Marijuana said "It has been bothering scientists for years now what, in fact, caused this morale-sapping condition for men. These noisy 15 yr old boys came up with the theory as a joke for their GCSE Religion Coursework, but actually solved a life-long question."
Dr Marijuana has recommended breast implants and liposuction for the 61% of women who are overweight, and a shovel in the face for those who are just plain ugly.
He continued, "Many of the women in this country are in full-time careers now and claim not to have time to get themselves sorted for their partners. This attitude is very disappointing as many women who work full-time are still hot. There can be NO excuses!!!"
This is likely to cause outrage to feminist (lesbian) groups and Catrina Ruane who is still undecided on her stance on the issue, as she is still working on a replacement for the 11 plus in N. Ireland before the end of time.
