Yes. Antibody levels fall off rapidly after an infection; but your longer term immunity is provided by other various cell types remembering the virus/etc. The difficulty is that while anti-body levels are easy to measure, testing the response of the various memory cells can only be done by exposing them to the infectious agent again in a test tube/etc and looking to see what happens.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I've got an Eagle classic traffic light, and I want to get a controller on it so that I can make it do a proper light sequence as if it were on the street corner. I see a bunch of controller boards that somehow must allow for user input for the time parameters, and while that would be nice (and where would that board be installed?), I would also like the ability to be on a nearby computer and be able to control the lights manually.
And if this works out, I might try this with X-mas lights. I guess I am looking for ideas here.

I see they're 120V but not familiar with them at all.
If the lights are lit separately from the controller I'd say get a 4 channel relay board, a micro controller and program the thing yourself. But that's just eh way I would do it.
I based a programmable xmas light controller on this a few years back and it worked pretty good.

Back in the 80s did a similar thing with my mate to control lights for a disco in the school. We used triacs rather than mechanical switches and 8 channels of lights controlled by a port on a Vic20.
Worked great, until we connected it up to 500W stage lights (sometimes two at a time) and the triacs all melted!!! Add one huge aluminium heatsink and voila!
The super-duper improved version used a multiplexer to give a whopping 256 channels and used a chip that could turn on and off at specific points in the mains cycle (each cycle) to give dimming capabilities and the mighty C64 took over from its little brother.
Those were the days...

Yeah had a lot of fun in those days, things were much simpler and so was I.

Nope, but I was looking for something like that around 2007.
I wanted a simple display for the call center -- to indicate the health of the system I was working on at the time.
With essentially no user interface, there needed to be a way to indicate a problem to the supervisor.
Eventually, I wound up with a simple box with red, yellow, and green LEDs -- attached to the parallel port of the supervisor's PC.
Because I was writing the system for a taxi company, I would have preferred a "real" traffic light.

Soft and soothing music helps, like Memory Metal.

I'm doing some code archeology on some old code written at the time when .NET was launched, and one of the really cool things was how you could write UserControls for the web and they would automatically be rendered based on the device. So for a webpage, they'd render as HTML. For a mobile device they'd be rendered as WML (Wireless Markup Language).
We put a ton of energy into writing a bunch of CodeProject code to support this back in the day, and every so often I stumble upon a small relic of this. It's like cleaning out a basement and opening an old cupboard only to find you still have a coal shootchute.
Edit: My abject apologies for writing "shoot" instead of "chute". Talk about being distracted by the news...
