Once again I am thinking of all those "ecologically responsible" Greenie cyclists. They could really lose their juju if they do too much of it. Article below from from: J. Sex Med. 2005; 2: 596-604:

Bicycle Riding and Erectile Dysfunction: An Increase in Interest (and Concern)

By Vincent Huang, MS, Ricardo Munarriz, MD, and Irwin Goldstein, MD


Introduction. From 1999 to 2004, there had been 21 publications from multiple medical specialties (sexual medicine, urology, neurology, cardiology, biomedical engineering, sports medicine, emergency medicine, and officials from the National Institute for Safety and Occupational Health) investigating the relationship between bicycle riding and erectile dysfunction (ED). In the previous 18 years, there have been 14 such studies.

Aim. The primary aim was to summarize accumulating data on the safety of bicycle riding based on medical evidence categorized by levels of evidence, including case reports, observational studies, case control studies, mechanistic studies, and population-based epidemiologic investigations. The secondary aim was to address the concerns of bicyclists and propose measures to minimize the risk of ED associated with bicycle riding.

Methods. An English-language medical literature review was made of publications in peer review journals from 1981 to 2004, including published abstract presentations at major medical meetings.

Main Outcome Measure. Ranked published epidemiologic data on bicycle riding and ED.

Results. Bicycle riding more than 3 hours per week was an independent relative risk (RR = 1.72) for moderate to severe ED. In case control studies, the prevalence of moderate to severe ED in bicyclists was 4.2% and 4% vs. age-matched runners 1.1% (P less than or equal to 0.018) and swimmers 2% (P = 0.05), respectively. Therefore, bicycle riders should take precautionary measures to minimize the risk of ED associated with bicycle riding: change the bicycle saddle with a protruding nose to a noseless seat, change the posture to a more upright/reclining position, change the material of the saddle (GEL), and tilt the saddle/seat downwards.

Conclusions. The mechanism is hypothetically related to the rider interaction with the bicycle saddle at the perineum to saddle interface. Straddling bicycle saddles with a nose extension is associated with suprasystolic perineal compression pressures, temporarily occluding penile perfusion and potentially inducing endothelial injury and vasculogenic

Disaster losses have increased dramatically in recent decades. Yet as discussed here frequently there is no scientific evidence showing that any part of this increase can be attributed to changes in climate, whether anthropogenic in origin or not. This is a long post on this subject. It contains a lot of gory detail on what I consider to be a major misuse of science in the climate debate, viewed through the lens of a recent paper in Science.

I focus on this issue mainly because this is an area where I have considerable expertise, and in this context my work is often mis-cited or ignored. This misuse of science is pretty much overlooked by scientists (here is one exception) advocates on either side of the debate, and the media (here is one exception).

A number of colleagues and I have a letter on this subject coming out in the November Bulletin of the American Meteorological Society (I'll post a pre-publication version of this soon). Also, in partnership with Munich Re we are organizing a major workshop on attribution of causes underlying the observed trend of ever-escalating disaster damages. Munich Re seems very supportive of rigorous science on this topic. So clearly, I intend to pursue this subject.

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is to promote themselves as wiser and better than everyone else, truth regardless.

Global warming has taken the place of Communism as an absurdity that "liberals" will defend to the death regardless of the evidence showing its folly. Evidence never has mattered to real Leftists
