I don’t recall ever seeing this listed as a Parkinson’s symptom or as a side effect of any of the meds I’m on, so this may and/or may not be germane to this blog, but…
I fart a lot.
No, I mean a LOT, as in “Cedric’s extreme farting transformed a lovely home into a vacant LOT.” Luckily (and this one is definitely attributable to Parkinson’s) I have no sense of smell. Unluckily (but logically) all this gas tends to come out when I’m physically active – i.e., at the gym. Jumping jacks are the worst: what would normally be one or two big but concealable farts becomes a series of four or five short, loud bursts. These bursts occur rhythmically, almost as if they were an intentional part of the exercise. Come to think of it, I know nothing about the history of jumping jacks. For all I know, jumping jacks were originally developed as a way to ‘encourage’ the body to release excess gas.
On a related note, my dog Bear burps almost as much as I fart. Together we form The Household of Rude Noises.
