That'd be pretty great. the number of tickbites is certain to decrease, and, if it's identified as a major thread, can certainly be avoided almost entirely. But it's only been published in a single paper called "Medical Hypotheses" and there are a number of other diseases mentioned as possible causes: "In both AD and/or the tSEs, transmissible agents and infectious proteins have been postulated to be aetiological factors [4], [8], [11], [12] and [13]. These include bacteria such as Chlamydia pneumoniae [14], Borrelia burgdorferi [15] and [16] and Spiroplasma sp., a helical mycoplasma in scrapie [17], typical and atypical (unconventional) viruses [18], e.g., Herpes simplex virus [19] or L-particles of the latter [19] and [20], tobacco mosaic virus [21], retro-viruses [22], viroids and plasmids [23] and [24], virinos [25], scrapie-associated fibrils [26] and [27] and others [28] U.

Should be easy enough to ask a sample of patients and a control what diseases they had and how much time they spent outdoors. So easy in fact that I'm sure it's been done and nothing came up.
I'm sure you're feeling really smart now, having repeated the endless slashdot correlation does not prove causation meme. It's so great that every 14 year old slashdotter seems to know more about statistics than scientists do.
You're even closer to your "best of slashdot" award by not even reading the summary, or not knowing what "corrected for physical activity" means. But beware: the hundreds of "BMI is stupid because I'm not fat/It's all muscle/my bones are heavy" commenters are on your heels. It's surprising that there's not a single really overweight person commenting here, considering that 90% of overweight (by BMI) are simply fat. But maybe, just maybe, all the geeks here are secret superheros.
I should add that there's a problem with the general sentiment of "everything was built so much better in the past". Firstly, that might simply be cognitive bias. The old stuff that lasts is still around so you'll base your judgment on that, neglecting everything that broke down and is long forgotten. Secondly, it's not that we have forgot how to build solidly. We've just learned to build cheaply. Plastics just weren't available in the past so you had to use metal. There was less knowledge about materials so you had to use higher margins or error. All those factors drove up the prices. Your grandmother's washing machine might have lasted twice as long, but it was three or four times as expensive. With longevity comes stagnation - I don't even want to use a twenty year old fridge, as it'll be loud and wasteful (even if you include energy used to manufacture it).
Sometimes you might want something solid just because it's more fun to have it. It might be furniture, tools or even notebooks. But there are still brands around to cater to that need, it's just that most people prefer to buy the cheap stuff and then bitch about i. e. Apple's prices.
In any formula, constants (especially those obtained from handbooks) are to be treated as variables.
