From what you have described, the urge to "pop" your back is a result of holding a static posture for extended periods. Leaning over a desk for prolonged periods would be considered a static (or unchanging) posture. It is healthy and advisable to move around a little at least every 20-30 minutes, get up off your desk and stretch quickly (it only takes 30 seconds to stretch). Every 30 minutes try standing-up, stretching your hands over your head as high as you can, pushing your chest out, and looking up at your hands at the same time. This will stretch-out your back and allow the joints to replenish the synovial fluid that is required to keep those joints healthy. If your spine "pops" a bit it is nothing to worry about, and is a natural thing.
There is most likely nothing wrong with you. If you are overly concerned, go see a chiropractor in your area for a check-up.
It has been recently reported that the Big Ben Clock Tower is leaning slightly. This would indicate a problem with the foundations below the tower. It is being looked into for a reason why.
If you mean 'Is the Leaning Tower of Pisa in Italy?' then that would be a yes
You would see the leaning tower of Pisa in Pisa, Italy
If you mean 'when the Earth is leaning away from the Sun', the answer would be winter

Underneath the Leaning Tower is clay. The clay on the side that leans is soft, which caused it to sink. They hoped that the clay would harden but it did not.
Because otherwise it would fall over.
The Leaning tower of Pisa, which is in Italy, is famous for its lean. Even if it didn't lean at all, it will still be famous because the tower of Pisa is a cathedral of Italy, or also known as the bellchamber/belltower of Italy.
Sexual urges are stronger than hunger urges, most people would say. But, like everything in life, sex has a time and place. When hungry, thirsty, etc. we aren't thinking about sexual urges. Sex and masturbation is like using a spice on food---a little is nice but you wouldn't want the entire spice used every day.
