I don't think this person intended it this way, but I do find this a bit condescending. I know for myself I currently have a decreased capacity to cope with the everyday stressors of life (let alone the stress of trying to get into med school!!) because my main hobbies that I use to manage my stress have been taken away due to covid. While I think a lot of us would always be stressed about the button thing (regardless of whether or not there was a pandemic going on), I think that most of us are used to having more things to direct our energy towards. Without those things, it's only natural we would latch on to something we can put a concerted effort into.
I can see their point for sure, and definitely the level of neurotiscm may not be ideal, but can you really project from a premeds behaviour to how they'll be after 4 years of medical school and a 3 year ER residency or 5+ year surgical residency? That seems a bit ridiculous, especially considering many of us are very early twenties and still developing our brains.
