Scenarios are not restricted to one session only and will not stop simply because a visitor logs out or otherwise ends her session. In the example shown above, if a visitor logs in but never displays the /Snowboards page, information about her scenario state will remain indefinitely in the profile database.

In general, limit a scenario’s lifespan wherever possible.
