It doesn't matter when the last time I used it was. The exception being if I force closed an app. That app won't get started again unless I start it. Task killers apparently don't actually force close the apps, if anything they do a kill.
I can't tell you what the difference is between force closing and killing on Android, (maybe it's a kill -15 vs a kill -9) I just know it's different because if I use a task manager to kill it, it will eventually restart, if I force close it, it will not.
