Time Travel Safety Tips

1. Be careful to ensure that your wormhole is geo-stationary. Otherwise, you may find yourself embedded in other objects, or in deep space.
2. If traveling back in time, you may encounter yourself or others you know at an earlier time. Do not reveal anything about events subsequent to/prior to this meeting.
3. Do not injure or impair your earlier self, or any ancestors. This is particularly true of grandfathers.
4. You may encounter causal reflexivity, also known as causal circularity. (A causes B, which in turn causes A.) Deal.
5. Bring plenty of spare batteries.
