Actually, a better way to put this. Just switch the meanings of survive and to live. I think that applies better.

You can be surviving at a low level, in other words be barely alive. You don’t feel much, you’re probably sick all the time, and your physical condition is barely decent.

You can survive at a normal level like most people. You can feel everything and react to things, however it might not always be the best reaction, also you are easy to get sick, but it’s not *too* easy. So you’re alive, however not too alive or surviving at an optimal level.

Or you can be surviving at a very high level, where you enjoy everything, everything feels alive, it’s hard for you to get sick (because you’re surviving better than the virus or whatever) and your body is in much better state than most people. In other words you’re very alive, and surviving at a very high level.

I think that explains it better. πŸ™‚
