I found this online and have meant to post it for a while:
Like Peat, Russell Eaton calls cardio "breathless exercise". He also explains using scientific studies how it is linked to cancer, heart disease, aging etc.:
"By 'exercise' we mean any physical activity that is sufficiently vigorous orsustained to make you breathless and/or sweaty; this is the usual understanding of the word exercise.¬† On the other hand, physical activity that does not make you breathless/sweaty is good for the body and very healthy.
The latest research is clearly showing that exercise shortens life expectancy,is bad for health in general, and causes a host of problems, such as osteoarthritis, cancer, diabetes, heart disease, premature aging of the body, and weaker bones to name just a few of the issues."
