Sims Autonomy - What do they do, what don't they do?

Yes, my Sims do fish autonomously. Mind you, it's not necessarily the active family. I play a rotation save and the second family mom in the rotation, is often seen near the residence of the first family, fishing away. A much older and now discarded incarnation of this save, my young Mom in my active family, would attend her garden, vigorously. She was dedicated to keeping her 'crops' in good health. LOL
