Sure, buddy. And not wearing a helmet would doubtless make you a better motorcyclist, too. Fortunately, in the case of motorcyclists, people who actually believe this tend to kill themselves earlier, sparing the rest of us from having to listen to their bullshit.
Note that I'm still wearing the seatbelt, and I'm not pushing for the repeal of seatbelt laws. If you'll read a little more carefully, you'll see that my objection is to the mechanical change in handling, visibility, etc, just at the moment when you need it the most, not to the presence of safety measures in general.
Edit: I suggest not slouching to start with.
