My old iPod Classic survived a washer cycle back in 2009, still spins up fine today.

Were those three tenants all in the same industry or sector? When we saw a big drop here it was clustered, one tech firm leaving started a chain reaction because the other two were tied to the same clients or contracts. If yours is spread across different types of businesses, that's a different problem than if it's all coming from one failing sector. Also curious if your building has any big floor plates that are just hard to split up for smaller tenants. That's been our issue, nobody wants 50,000 square feet anymore but they also won't take half a floor with weird column spacing.

Was it really that dangerous though? I mean a chain skip on a hill is annoying but you made it sound like he almost died.
