BBC News - Being overweight or obese 'linked to 10 common cancers'
BBC News - Being overweight or obese 'linked to 10 common cancers': Scientists calculated individuals carrying this extra weight could contribute to more than 12,000 cases of cancer in the UK population every year.
So if you had something which could help people loose weight and keep it off then would you use it and would you complain if it was funded ?

Perspectives and images of cycling as a barrier or facilitator of cycling
Sounds like a good justification for cycle monorail like system.. ( read on).
Perspectives and images of cycling as a barrier or facilitator of cycling: The public images of cycling can act as barriers or facilitators of cycling. This qualitative study explored images and perceptions of cycling, their potential influence on cycling and whether these views differed between regular, occasional and non-riders.
Seventy participants (24 males and 46 females) were recruited. Of these, 22 were classified as non-riders, 23 were occasional riders and 25 were regular riders. Twelve focus groups were held in inner Sydney during October and November 2005. Data were audio taped, transcribed and thematically analysed.
Themes linked to images of cycling included: ‘clean and green’; ‘healthy and fun’; ‘dangerous’ and ‘serious business’. Themes linked to images of cyclists included: ‘risk takers and law breakers’ and ‘status and sub-cultures’. Discussion centred on the low social status of riding over other transport modes, the relative acceptability of different riding sub-cultures, the ‘green’ image of cycling transport and the status associated with the riders clothing and bicycle choice, especially lycra and its ‘serious and sporty’ connotation.
While ‘cycling’ was generally viewed as a positive, environmentally friendly activity, the actions of some ‘cyclists’ were disliked, which influenced views about cycling, particularly among non-riders. A cycling acceptability hierarchy emerged; with recreational riding at the top, followed by cycling for sport and exercise, with transport/commuter cycling towards the bottom. Bicycle couriers were viewed least favourably. A common perception among non-riders was the latter two groups were rule breakers and risk takers, while regular riders felt unfairly judged by this stereotype.
While there was greater acceptance of recreational riding, riding for transport was not viewed as a mainstream activity. There is a need to improve the public acceptability of cycling and change public norms so it is seen as an everyday activity that can be undertaken by almost anyone, without the need for special clothing, expensive equipment or limited to purpose built facilities.

Health benefits of cycling: a systematic review
Another review - verdict yes.
P. Oja1, S. Titze2, A. Bauman3, B. de Geus4, P. Krenn2, B. Reger-Nash5, T. Kohlberger2
The purpose of this study was to update the evidence on the
health benefits of cycling. A systematic review of the
literature resulted in 16 cycling-specific studies. Cross-
sectional and longitudinal studies showed a clear positive
relationship between cycling and cardiorespiratory fitness in
youths. Prospective observational studies demonstrated a
strong inverse relationship between commuter cycling and
all-cause mortality, cancer mortality, and cancer morbidity
among middle-aged to elderly subjects. Intervention studies
among working-age adults indicated consistent improve-
ments in cardiovascular fitness and some improvements in
cardiovascular risk factors due to commuting cycling. Six
studies showed a consistent positive dose–response gradient between the amount of cycling and the health benefits.
Systematic assessment of the quality of the studies showed
most of them to be of moderate to high quality. According to
standard criteria used primarily for the assessment of
clinical studies, the strength of this evidence was strong
for fitness benefits, moderate for benefits in cardiovascular
risk factors, and inconclusive for all-cause mortality, cor-
onary heart disease morbidity and mortality, cancer risk,
and overweight and obesity. While more intervention re-
search is needed to build a solid knowledge base of the health
benefits of cycling, the existing evidence reinforces the
current efforts to promote cycling as an important contri-
butor for better population health.
What I find interesting about these Scientific papers is that they frequently balance the advantages of cycling against increased intake of car pollution. Naturally and elevated cycle would not have these problems, but it is interesting that the problems are worse if you are actually a car driver/ passenger.

What would you do to stop 4,267 people dying in London?
From a government report calculating the pollution impact of 'fine particles' ( the kind emitted from diesel engines ).
"It is estimated that fine particles have an impact on mortality equivalent to 4,267 deaths
in London in 2008, within a range of 756 to 7,965. A permanent reduction in PM2.5
concentrations of 1μg/m3 would gain 400,000 years of life for the current population
(2008) in London and a further 200,000 years for those born during that period,
followed for the lifetime of the current population. For the current population, this is
equivalent to an average 3 weeks per member of the 2008 population, with the
expected gains differing by age." (Dr Brian G Miller)
A switch to elevated cycle lanes would do a huge amount about this and a number of other problems. Something which an uptake of google driverless car's wouldn't help with.
Possibly Dr Millier is just a lone loon perhaps ? - no this evidence is used by this
http://www.whpara.org.uk/resources/PDFs/Air-Quality/Draft-Islington-Air-Quality-Strategy-2013-2016.pdf To justify the introduction of a no idling law in Islington London as mentioned here http://www.lbc.co.uk/islington-council-unveils-plans-to-fine-idle-diesel-drivers--94853
The net predicted result of all this is an increase in CO2 as people switch from Nitrogen Dioxide diesel.

So what would these 4267 lives be worth to you? How much would you spend ?
The actual answer is anything over a quid is pushing it. According to cycling Weekly we spend about about £1 per year head of population. What would happen if we got the price of an expensive coffee from everyone to improve cycle lanes ( elevated or other wise)?Cycling and the city: A case study of how gendered, ethnic and class identities can shape healthy transport choices
Cycling and the city: A case study of how gendered, ethnic and class identities can shape healthy transport choices
Cycling and the city: A case study of how gendered, ethnic and class identities can shape healthy transport choices: However, it relies on the cultivation of a particular ‘assertive’ style to defend against the risks of road danger and aggression. While the identities of some professional (largely White) men and women could be bolstered by cycling, the aesthetic and symbolic goals of cycling were less appealing to those with other class, gendered and ethnic identities.

Cycle Atlanta: Interactive map
Cycle Atlanta: Interactive map
wow this is a veritable feast of information. This contains vector data showing the rides of many hundreds of cyclists in Atlanta. It's a fantastic insight into cycling in a very hot city.
