Is there any way to slow down the time in the game, but nothing else?

The problem is not that the time goes fast. The problem is that sims take too much time to do some things. For example, almost 2 hours to cook and eat a sandwich... or half an hour to take a fast shower... or whatever. The game isnt realistic, period. I think the time speed is just right, because its a game, but what i dont get it is why it takes so long to do some things that in real life, wont take more than a few minutes.
