Remember the old joke? "How do you tell a happy motorcycle rider? By the bugs in his teeth."
You ain't lived until you're going down the highway at 70 mph to have one of those big june bugs hit you in your unprotected forehead.... Liked to knock me off the bike.
I've lived then. Happened to me the first time I took my first ride on the highway, 25 years ago. Had a helmet, did not have a shield. Bought a face shield 10 minutes later
