Our building was built in the 50's or 60's, no concrete.
My upstairs neighbor has three kids...son in 6th grade (5'8", at least 250 lbs), one in 12th grade (5'4", at least 260 lbs), and an older daughter (6'0", bout 3fitty), and the mom is about 5'5", before her lipo, prolly bout 230.
The mom works early mornings, so she's usually up at like 3...the oldest daughter is a stripper (yeah), so she's getting in when the mom gets up. The youngest goes to school with my daughter, so he's up around 6something, and the daughter in the 12th grade is home schooled, so she's always there.
it's hell...pure hell...when they get to walking around it sounds and feels like we're on the bottom of a slave ship...CRUNCH CRUNCH CRUNCH BOOM! BOOM!
Sunday mornings you can hear the FBB (Fat Butt Boy) yelling and playing video games. They got a new stereo the other week and kept the volume up for two days straight...while they were out of town.
