You don't have 80cm between normal floor joists so installation in a regular house could be complex and expensive. If you are designing a multistory new build specifically for the elderly leaving a space for a solution like this to be installed/uninstalled in the future could be added to building standards.
PCR tests on Spanish sewer water found positive samples even earlier in 2019. I think the earliest so far French case was in early December 2019. I hope lots more studies are proceeding.
It is worth mentioning that you shouldn't lock a bike around the seat tube. A thief can cut the frame tubing much easier than the lock, disguise the break by covering it with a u-lock carrying clamp and still have a ridable bike to sell.
I used the Sheldon Brown method for a while. Nobody stole my bike but I gave up on it after getting a few broken spokes. A rigid lock resting on a relatively weak spoke is asking for trouble.
A cigarette contains up to a gram of tobacco with a nicotine content of 0.5 to 2 percent. A recent estimate of nicotine's human LD50 is in the range of 0.5 to 1 grams. A four cigarette dose would seem unlikely to be lethal.
Standing up while cycling makes your calves work really hard. A hour or two on one of these would make even a regular cyclist ache for a week, so a seat is probably essential for any practical purpose. The riding experience looks novel, that is probably it's main appeal.
Rockets without a payload are lighter and have greater range so you can attack more northerly targets - for example Tel Aviv. They are about public relations far more than they are conventional military weapons.
A frequent method of torture by US forces is to threaten to turn a captive over to allied domestic Police or Army forces. It is useful to look at the relevant UN conventions to understand what the legal definition of torture actually is.
Unfortunately Anti-trust action is often used to drag companies into the unholy Congressional Lobbying racket.That's the way it worked out with Microsoft. Google's lobbying budget seems to scale with it's size so maybe it will escape serious action.
I sit at a Dojo regularly and occasionally do introductions. We don't teach counting, but do teach following the breath at the nostrils and settling the mind in the hands, as things to come back to once the mind has wandered. There is some technical stuff about posture to learn but basically you just turn up and sit. If they do it differently somewhere else that's cool too, lineages vary.
With the school of Zen I am familiar with you pretty much do "just sit". The practice is called Shikantaza, literally "Just sitting" in english. With 10% chanting and bowing afterwards.
