You know what would be better *bats my fake eyelashes* if Stan actually started going gray by 19 due to having stress, an unstable food source, constantly on the run, and having to deal with the realization that he not only lost his best friend and brother, but his whole family. And it’s not like a lot of gray at first, no it’s a few strands here and there that he writes off as just the lighting, his bad eyesight, or maybe some of the chemicals he used for some products he sold. Whatever the reason, there’s always a reason NOT related to his mental or physical health.
But the moment he is in his early twenties, when he starts getting into more dangerous situations, meeting more dangerous people, THATS when its STRANDS of gray hair.
The lack of food, sleep/rest; the fact that he was always in fight or flight mode since the moment he was kicked out is all catching up to him and it starts freaking him out. (And if we include the fact that Stan was in the “loony bin” for a while, his stress levels must have been of the charts unless he was medicated, and even then with what we know and the Tijuana incident do you think Stan would have liked to be drugged, well although I suppose that depends on where in the timeline we place these two situations)
Regardless even after the portal incident and post faking his death where Stan no longer had to be on the run, had a stable living situation, and access to nutritional food, he STILL didn’t actually do much to take care of himself. He was a hardcore drinker and smoker who would manage a business during that day and at night teach himself advanced mathematics to build an interdimensional portal to save his brother. If anything he was probably grayed out by his early to mid thirties! (Which meant he probably had to dye his hair for a while until he was at a reasonable age to write his graying out as normal)
And while ford probably began going gray in his early to mid thirties (I imagine that having to constantly adapt to different dimensions and their environmental rules wasn’t easy)from what we have seen he was probably able to at least go a decade more or so before he himself went completely gray. (And with the nutritional pills i doubt that food scarcity/ lack of vitamins and nutrients was one of the reasons why went gray compared to his brother)
Idk why this triggered this out of brain lmao 😭
