I'm going to defend the lads to a certain extent on the spitting, but not the slow play.
Spitting and excessive production of phlegm or mucus is a result of many things, including allergies and impurities in the air, and a hypersensitive airway passage nerve endings. We all know that strenuous physical activity leading to deep respiration and eventually more mouth breathing inhaling than nasal as we get ampped up is normal. Also, asthma in many forms from that triggered by the air quality to exercise induced or stress induced causes plenty of coughing and clearing of the throat.
As one that produced a great deal of phlegm and clear mucous or spit either in exercise or stress, or in certain environments from when some woman is wearing the wrong scent and any of those airfresheners that say 'fresh' or 'mountain', there is something that gets me going and both coughing and wheezing.
So, take Bradley on the course, in the desert or at Riv in polluted L.A. or whatever the environment or stress that causes him to produce a lot of spit-mucus-phlegm, the only question is; what does he do with it? I'm willing to give anyone a 500-1 odds he doesn't have TB!
So I say, and as I do, spit the crap out on the grass. (certainly not near where you are respitorily near someone else breathing) but on the ground, which is a field of sporting play covered by turf that has no health problem with it. Maybe even some beneficial microbial activity is induced... I'll defer to a guy like Mahaffey on that!
I for one, given how much I produce, am not about to swallow that much sputum, mucus, etc. Any M.D.s that wish to weigh in on swallow or spit it out, would be much appreciated.... along with a private e-mail on any really great jokes that come to mind....
But, with Bradley saying he will try to modify his spitting, I'll give him credit that he is "trying" to not be rude. I didn't note him doing so much spitting at the PGA win, so I'm guessing it is environmental irritant.
