Likely referring to the Japanese-style bidet, aka washlet, which have a built-in dryer so zero toilet paper is required. But even a cheap one without a dryer will drastically reduce the amount of toilet paper required.

Yes, they're only called bidets for lack of a better word in English. Mine has adjustable water temp, heated seat, air dry, variable pressure, front/rear wash, oscillation, and several more modes I've not even dared to try yet. Got mine from Costco during one of their periodic sales. I highly recommend them even when there's no toilet paper shortage.

> going in a lockdown is the prevention measure to avoid mortality rate in the double digits…

Huh? Mortality rate is the mortality rate, its independent of a lockdown; unless more vulnerable people are "locking down" at rates different than less vulnerable ones, but at that point we're not talking about a "lockdown".

The purpose of the COVID lockdown wasn't to suppress the mortality rate; it was to suppress the total infected/mortality.

I suppose the mortality rate could go up if the healthcare system in a particular area is fully overwhelmed, such that significant number of normally treatable cases end up in death rather than recovery. The morbidity rate is probably less affected though.

In normal times the experienced mortality rate is based on most of the sickest people receiving supportive care in the hospital that greatly blunts mortality rate.

When your medical needs exceed resources mortality rate converges toward untreated mortality rate.

Try this on for size what is the untreated mortality rate of a single gunshot wound to the chest. Its close to 100% but the overwhelming majority survive with prompt treatment. You wouldn't say that the mortality rate was what it is.
