Sleep Like A Log

#111
Sleep like a log
- To sleep very soundly.
- To sleep heavily, long and without disturbance.

Origin:
This probably originated from the days of lumberjacks who used basic tools to bring down trees and then cut them into logs of different sizes. This required a lot of physical effort and the men slept soundly due to sheer exhaustion. As logs are large blocks of wood, they aren't easily movable. Possibly the lumberjacks would term their deep sleep as what the log does - no movement - and hence the term 'to sleep like a log'!
