Do zombies continue to age?
Of course they do. In fact, the leading cause of death among zombies are age-related diseases such as Arthritis (causing them to move erratically), Osteoporosis (causing random body parts to fall off), and Alzheimer's (causing them to eat brains). That's aside from skin cancer and insomnia, which are typical and crippling problems for many undead.
