Restaurants? I can take or leave. I don't mind saving a few extra bucks by eating at home. Ironically, the restaurant I miss most is the Chinese takeout place 1/2 mile away. Good food with excellent value on their lunch specials. They decided very early on to close for the duration. I don't know if some knuckle draggers were stopping in to harass and threaten them which forced their hand.
Gyms? Eventually. However, I haven't used a public gym in 15 years. I work out at my school's weightroom. It's far less crowded, but it's also far less clean and organized than a public gym. My experience with public gyms was that they were very clean, but I hated the crowd. Spraying and wiping down all benches and machines after use was always a requirement, but few things were more annoying than getting to that last lift and having to wait forever while that particular machine was in use.
Regardless, I know where I've been, but I don't know where some of the other people in public have been. I'm not concerned about dying from the virus, but I've got some loved ones who wouldn't fare as well if they contract it. I'll sleep much better at night knowing I'm not the one elevating their risk of infection. Additionally, I don't relish the thought of contracting it and causing someone I don't know to have to go into quarantine for awhile because of me.
FWIW, I had a relative die from complications brought on by West Nile. I had a former HS teammate contract encephalitis from a mosquito bite while in college. He had to be life-flighted when his heart stopped beating. He survived, but his quality of life instantly went in the crapper. His short-term memory got fried, his motor skills and speech have suffered, and he lost at least 1 standard deviations off his IQ. As a result, I'm more sensitive than most to all the supposedly random diseases.
