This may be an obvious question, however I can't find an obvious answer. Is rapid premature aging something we can assume is painful?
I'm not talking about 'natural' diseases such as progeria but rather being hit with an aging spell in a magical universe. Drastic age changes in the space of a few minutes/hours.
I know that as long as I am consistent and know my own universe rules I can do 'whatever' I want with Magic (Sanderson's 3 laws etc).
- The logical scientist part of me wants to know if your bodies cells age/replicate so rapidly would it not be expected to be painful?
- or would pain/lack of pain have to be incorporated into part of the spell?
I had two mental images in my head that are actually two different directions to approach this aging spell. However, in my mind, both would cause pain/discomfort or at least some sort of sensory overload mismatch signal in the brain. One more so that the other, I wasn't sure whether this pain was would have to be explained further or if I could just assume it was part of the process and not have to explain or dig further. Which is why I tried to ask the question with no magic specifics. I didn't want to get bogged down in how the magic worked, but rather in what I could expect from biology and the human body's reaction.
- The first mental image I had in my head, is that the person appears to go through the aging process right in front of you. For instance, go from age 25 through their 30's and into their 40's in a short space of time. The cells replicating rapidly one after the other.
- The second image I had was that the cell aging was rapid/immediate but the effects were delayed. Even though the cells were aging/aged right then and there, the physical effects to an outside observer where less noticeable (as mentioned by Demigan's puppy cancer giving answer :) )
The strength of the spell determining the speed of the aging, as well as providing most of the energy requirements for cell replication or transformation through handwavium. Although this was never intended for body growth as in aging from a child through to adult. That would have additional energy requirements that I understand would definitely be beyond the scope of this particular question.
The aging spell itself was also never intended to stop localised time, as I realised this had the whole 'how do I feed you and get rid of your poop' issues. I do have a really badly phrased question on just that issue if anyone wants to take a crack at it. That is why I didn't use the [Time] tag and rather stuck with the [biology] tag, as there was surprising not an [Aging] tag of some sort.
Thanks to all the answers so far. I hope this edit has made it a little less opinion-based by giving you a rough idea of what was in my head.
