When did people stop going out?

I have noticed as I get older, my friends and even my family have started to go out less and less. I ask my friends to go out and they always have an excuse as to why they don't want to. Even my family, I ask them to go out and they always have some dumb excuses why they can't go.

Don't get me wrong I totally understand that I may be the problem and if I am I would rather someone tell me to my face. But I am not the only one, some of my coworkers have noticed the same thing, it seems like people don't enjoy going out anymore.

I know that everything is really expensive but I am not asking to go out to lunch or dinner. I just want to go for a walk or something like that.
