The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

The study investigated various factors related to the death rate from pneumonia. The study included 110,792 individuals (aged 40-79 years) who were followed for 15 years.

Regarding walking, the study found:
(a) Those who walked less than 1/2 hour per day had a 30% increased risk of death from pneumonia compared to those who walked 1/2 hour  per day.
(b) Those who walked more than one hour per day had a 30% decreased risk of death from pneumonia compared to those who walked 1/2 hour per day.

The results from the study show that an increase in walking time is associated with a reduced risk of death from pneumonia.
