The longest recorded time a person has been on a life support machine is over 37 years. Paul Fairbanks, of California, was on a ventilator from the age of two until he passed away at the age of 39 in 2017.

There is no time machine in real life. Except clocks.
The larger PDA phones such as the Blackberry tested out as having the longest battery life.

No, currently the longest at any time is 12 months.
