Who defines "good hands"?

How do you assure the dictator stays good (corruption, dementia, general personality shift)?

What happens if the dictator is no longer good (died, see above, the world has changed and the dictator can not adapt)?

Sure the dictator can assign ministers for topics outside of their skillset and similar and a head physician to determine when a replacement is needed due to health reasons etc, but a dictatorship is always unnacountable. What if the physician coludes with the vice-dictator to declare the dictator unfit? What if the dictator is actually unfit but accuses the physician of colusion? It has no safety checks against its rulers other than revolution and coup.

Democracy has flaws but so does dictatorship and they are not limited to "what if dictator evil"

But what does that mean? Does Australia span all timezones? Take its zone of UTC+9:30 and then go all the way around the globe to the east until you hit UTC+8 which is also Australia. Congrats you passed through all timezones and are in Australia again.

In germany the lottery is state owned and the tax is applied before money is added to the jackpot. So if the jackpot is 50mil you get 50mil

There are many breeds of cattle. Some which are on their own for most of the year. I am sure with some carefully selection (and maybe a few generations of crossbreeding) there could be viable breeds for reintroduction to most biomes which historically had wild cows
