What a sad world where someone's idea of "living it up" is to throw old sinks off a roof. I feel sorry for you and your life if that is the best you can come up with for fun.

Can you imagine the noise from a plant that size in full operation? I did a job for a small stamping firm in southern Ontario, and just standing in the parking lot it sounded like an earthquake starting up! A rhythmic rumbling that you could physically feel coming up from the ground.

My dentist when I was a kid had an xray machine exactly like that, except that the end of it was covered by a plastic cone. I always thought it was a drill and it terrified me - I thought "no wonder people are afraid of the dentist if they put a drill like that into your mouth!" I didn't have a cavity until I was a teenager and found out then that it was an xray machine and not a drill - boy did I feel dumb!

I don't believe it's a door - I think it's a window cover, as in the description.

According to the NHS: "A high dependency unit (HDU) is an area for patients who require more intensive observation, treatment and nursing care than are usually provided on a general ward. It is a standard of care between the general ward and full intensive care."
