Nano tech
Part of the idea for #1 is that you perform a test that reports back in under an hour, then for your case of strep throat, rather than dosing you with antibiotics that the bacteria become immune to, they instead dose you with a species of macrophage that targets that particular batch of bacteria. Give the bacteria infecting you an infection, essentially.
That's certainly a form of nanotech, but I think the programmable robots you're thinking of are a long ways off.
The US sterilization program served as a model for a certain European nation's "genetic purity" laws, even, so you weren't the only one to have this idea.
Oh my, that's pretty... progressive. The incidents I heard about in class for the eugenics programs was that they would sterilize the retarded/mentally ill. I'm pretty mixed about some of that stuff - On the one hand, you could say 'what a horrible thing, they can't consent, they don't know what you're doing'. On the other hand - these are essentially kids in adult bodies. Incidents happen, and due to health and mental reasons a pregnancy isn't a good thing for them. You can preempt some issues with a tubal litigation.
eflatminor - I have to disagree with you. Filtered water? Not going to do much. Our bodies are naturally designed to handle all sorts of stuff in the water. Fruits&vegies, yes, quite a few people could do with more of them. As for 'chemicals' - even purely organic food contain chemicals. Vitamins are chemicals. Water is a chemical. On the genetic angle, being born with Type 1 diabetes is genetic. You WILL NOT SURVIVE if you don't take drugs to treat that. No, there are NOT ALWAYS natural cures. Yes, we do need to look at bit more at them, but I'll point out that the first 100 years or so of medicine involved seeking out the active portion of various natural treatments to refine and increase the effectiveness. Willow bark tea led to aspirin. Cowpox lead to the smallpox vaccine. A mold lead to penicillin.
As for the male contraceptive/female viagra, would that really revolutionalize medical treatment?
HankB - Good response.
1. Interesting, would this be part of standard preventative care? Go in and get cleaned out every couple of decades starting at 40? A daily pill?
2. Personally, I think that macrophages are the way to go. A virus targeting the bacteria that's infecting you. Drip it in, the bacteria colony gets 'sick', and is unable to resist the mounting defenses of the body.
3. I've also advocated the 'once a month' shot whenever they come in for their check.
