Soaking seeds before planting helps you to break down the seed's natural defenses against what it expects from Mother Nature, which then allows it to germinate faster. Another reason is that while Mother Nature actively assaults seeds, she also gave those seeds an internal gauge to help them know when they should grow.

Is it worth planting old seeds?

I'm not necessarily recommending out-of-date seeds as being better than, or even as good as, fresh seed. Old seed often has sporadic or very slow germination, and sometimes the plants which do grow are a bit weak and wobbly. But there are many good reasons to keep hold of those old packets.
