The humans part is true. However, (and I could be wrong, I look at a lot of Undertale fanon comics) It is stated somewhere (uncertain whether canon or no) that monsters age through their offspring. When a monster has a child, the parent's magic flows into the child and out of the parent. This causes aging from maturity to death on the parents' part, and aging from infancy to maturity on the child's part. This is why Toriel is still alive and intimidating to the monsters in the Ruins, and Asgore is still fit to be king. Asriel died, so their magic has nowhere to flow. A lot of this or all of it could be complete bullcrap, I can never tell.
