When I was in year 5 the kids in the class had been working cutting apricots and they bought tonnes of candy and these whistles they were blowing all the time.

How much did the whistles cost ? one cent.

From the questions people ask and from online accounts.

Electrical, plumbing, HVAC are all pretty solid.

Heh no. All of those are being automated and dumbed down.

In a few years all you’ll need is an unskilled labourer and a robot.
