Marijuana is a gateway drug to cocaine, then heroin. There's some place to go when you're clocked the level. But once you've mastered TV, that's it. Nowhere to go or level up to... TV is the final product, it's the gateway to nothing. If TV doesn't give you your jollies anymore you have to go find a new drug to keep you agitated and alive on the inside like stamp collecing, your family, nature, fast cars or crime.
For your own safety artificially arrest your devolpment before you find yourself robbing a bank, or worse making babies, just to re-find the simple glee you used to get from Glee.
