i might as well stop for a big mac on my walk home

A Queens University (Belfast) study published today in the journal Heart purports that “[m]oderate exercise such as half an hour of brisk walking five times a week is unlikely to prevent an early death from heart disease, say researchers…. Only vigorous exercise such as jogging and hiking seems to make a difference.”
“Moderate [e.g., golf, digging (?) or dancing] and light [walking, bowling or sailing] levels of regular exercise had no impact on death rates from all causes or specifically from heart disease.”
So I finally get myself motivated to start exercising by walking the mile and a half to and from work every day rather than driving (ok, motivated because my car stopped working), and now I find out that I’m just gonna drop dead of a heart attack anyway. Looks like there’s no point in refraining from eating the bacon big boy.
