Like all plastic, I think it would. This also varies depending on what kind of plastic it is.
I have personally seen old ski boots fail during use on the ski hill. I can't give an exact number of years, however, the plastic does degenerate over time.
Absolutely! I met a nice couple in a hot tub at the resort I was at and the man said that his dad was skiing and jumped off the lift and when he landed his 20 year old boots shattered like glass.
Brittle?

The rubber or plastic seals become brittle with age and crack, or simply wear out.
PVC is kind of brittle to start with, though it becomes more brittle with age if exposed to sunlight, because UV rays break some of the bonds in the molecules. "Vinyl" (flexible PVC) is flexible because it has additional compounds called "plasticizers" added to it. Over time, these can leach out, again leading to a more rigid and brittle material.
The thickness of the shell (lip) increases with the age. This is how you can determine the age of the conch.

Your bones become more brittle (more porous and easier to break), they obviously stop growing, the rate of regeneration is slowed.

As we age, our bones tend to become less dense, making them more susceptible to fractures and breaks. This can lead to conditions like osteoporosis, where bones become brittle and fragile. It's important to maintain a healthy lifestyle with adequate nutrition and weight-bearing exercise to help slow down the natural aging process of bones.
You start boot camp at whatever age you join the military. Seventeen is the youngest that you can start (and you need parental permission).
