You are older than : It means you are older than 10 as degenerative changes can be seen as early as 10. Years old and continue as you age. The lowest 2 levels of the spine are the most involved, typically. This is the l4-5 and l5-s1 levels. These are age related changes that are significantly accelerated if you smoke and/or obese.
