Google has a feature you can enable where if they detect no activity on your account they will send several notifications over a set period of time, like 6 months or so. If you respond to none of them then they will give access to your account to people you configure. Essentially you have to ask yourself if there will be a period of time in the future where you know won't use your account for that long. If so then you should disable the feature.
