Everything Sims 2

1.) Veg Out Enabled Also For Couch Potatoes by Hexagonal-Bipyramid

Sims with the Couch Potato trait can Veg Out and do some other sofas/loveseats interactions (extremely lazy Sims can also do these).

2.) Workout Pack by Hexagonal-Bipyramid

Couch Potato Sims lose more comfort and energy. They also lose fun (the cheaper the exercise equipment is, the more fun they lose). You can see them struggle a bit more than non Couch Potato ones.
