Even if (and I'm not sure it does) that works for [math]\mathbb{R}[/math] (I'm assuming you can somehow make it work because of the no exotic smooth structures thing), I'm pretty sure it collapses for [math]\mathbb{R}^4[/math], and then you need to add a bunch of autistic axioms specifying which functions are differentiable.
Also, geometric definitions are nice.

Do you guys know anything about the topic of ACE2 gene expression and how it relates to novel coronavirus? It's been noted that you are more susceptible to the harmful effects of coronavirus if you smoke tobacco. I am wondering if that's also true if you smoke weed, but I've had trouble finding any information that I can understand to confirm or deny that. I've stopped smoking weed since just to be safe, but would like to resume if possible. I do creative writing work and music composition and weed sets my brain on fire.
