I remember a paper referring to a study in Scotland regarding the gastronomy tube and very high death rate of 25% and then remembered the Scottish games, wherein one event involves individuals tossing around telephone poles. The higher death rate might well be linked to larger size of Scottish people, though the report might not have indicated same. Never the less, as I would suggest, not only should ALS patients tone down the jogging, avoid, too, the caber toss until an ALS cure is found and you have full recovered.
