Article Abstract:
Male fertility diminishes by a considerable degree with age, according to research announced on 1 August 2000 that for the first time attempted to measure the decline in fertility in men with no known problems in this area. Research covered families of babies born in the Avon region of the UK between 1 April 1991 and the end of the following year. Information from the Avon Longitudinal Study of Pregnancy & Childhood data was examined by Brunel University and Bristol University in the UK and found that the capability of a male to father a child diminishes from the age of 24, six years before a woman's fertility declines. The chances of women with partners that are older by five years were less likely to conceive inside 12 months compared with women with partners of the same age or who were not as old.

Article Abstract:
UK motorists are receiving inconsistent advice from doctors, ophthalmologists and opticians over whether or not their eyesight is good enough to allow them to drive, according to a study by the Sheffield-based Royal Hallamshire Hospital. Research covering 100 people found that 26% of those possessing 6/9 vision failed the standard visual test for car driving, reading a number plate at 20.5 metres. Of the family doctors asked what advice they would give to people with 6/9 vision, 75% suggested they could drive, with 13% saying they should not. Of the GPs asked, 21% said the poorer 6/12 vision patients could drive, even though around 65% had failed the test.

Article Abstract:
Oxford University's Dr Leslie Iversen has dismissed the severe addictiveness together with the infertility and mental illness problems associated with using marijuana as myths. Cannabis is classed as a safe drug in Dr Iversen's The Science of Marijuana book, which states that it is safer than aspirin and does not lead to brain damage or cancer. The research will put further pressure on the UK government to look again at moves to decriminalise the drug, an active part of which could be used to treat people with acute pain and with Aids.
