# Multitasking is possible when we have extra capacity
Multitasking is an impossible task, but it is achievable when the conditions permit it.
For example, I'm able to safely drive and have a conversation at the same time. However, Talking while driving is dangerous when the other person can not observe the traffic situation.
From this example, there are two factors that make multitasking possible:
- The difficulty of the task: The ability to divide attention depends on difficulty of the task
- How well-practised the task is: The ability to divide attention can be achieved with practise

Also, people can simultaneously drive, have conversations, listen to music, and think about what they're going to be doing later that day.
