That was the trouble: he would suddenly find himself driving his car on Route 50, or in the garden with wateringcan in hand, and have no idea why he was there.
People can still water their gardens with a wateringcan and wash their vehicles using a bucket and sponge, which use a fraction of the amount of water that a hosepipe or sprinkler does.
For example, Egyptian researchers have shown that by transferring a single gene from barley to wheat, the plants can tolerate reduced watering for a longer period of time.
