I'm not afraid to discuss them in real life, but I discuss my medical issues more openly online. Mostly because I don't want to just whine about my medical issues.
I'm also more open to sharing private information like, I've never felt that I belong to any gender (and this led to a lot of anger and frustration for me growing up). That's becoming more accepted now, but I was never part of the LGBTQ+ community and I don't feel like it represents me particularly well. I'm just kind of neutral and don't want to be associated with any sort of gender identity or movement one way or another.
I've always found the new car smell to be very unpleasant, which makes sense since I'm pretty sure it's just a bunch of chemicals off-gassing.
