Fabulous opinions and ideas already noted here. In my youth, I was guilty of riding in less-than-desirable attire, and have seen people fall down in front of me, and slide on the pavement. I took those experiences to heart. You are all individuals, and free to make your own choices. Here's something to ponder.
A certain lady, age unimportant, is having a bad day. She may have PMS, or be in the initial uncomfortable stages of menopause. Her husband left her two years ago for a younger, shapely, libidinous piece of arm candy, and left her with car payments, child care duties, and a bad attitude. She is not a lesbian, but right now she hates men more than Charlie Sheen hates rehab. She works miserable rotating shifts as an emergency room nurse, at a hospital that hasn't given her a raise in three years, and could care less if she leaves or not. She's seven hours into her current shift, and on the way to work today, her car's check engine light came on, and the car made a few horrifying mechanical noises, and quit running eight blocks from the hospital parking lot, in the rain. Her teenage kid refuses to answer his phone, because he's in her basement, playing video games with his loser friends, so she may have to walk home. She's having hot flashes, has a screaming headache, and just got done providing medical care for a drunken redneck who broke his hand trying to punch his toothless wife, but hit the refrigerator instead. And the head nurse just told her that she's going to have to work the Fourth of July this year.
NOW.......here you come into the emergency room, having just fallen off your macho, masculine, small-weiner-compensating two-wheeled phallic symbol. You thought that you were invincible, and the greatest rider since Mike Hailwood, and safer that Ralph Nader's nanny. You weren't wearing protective gear, because, after all, you were just running down to the corner store to pick up some Preparation H and a bottle of Jameson's. And here comes Nurse Ratched. She's going to do her assigned medical care duty, and the first thing on her list is to make sure those little owees you have are sanitary. She's got a Home Depot bucket full of saline solution, which, I don't need to tell you, is essentially salt water. In her other hand, she's got a stiff-bristled brush that you could use to clean barnacles off a battleship. Guess what? You will NOT be happy with Nurse Ratched's technique. But rest assured, those wounds will be clean when she's done. And she'll be the one removing your first crusty, blood-stained bandages, giving you another scrubbing to remove the necrotic material, and re-applying your bandages.
Sleep well, grasshopper.
