Prehistoric Time

I've been documenting my neighbours. One neighbour would come home, have lights on until 7pm and then all the lights would be out until midnight, and then they'd all come back up again.

So...something like this.

2000~0100 SLEEP

0100-0400 WAKING HOURS

0400-0700 SLEEP

0700-1900 WAKING HOURS

I haven't tried this, but my guess is the day will feel much longer.
