Taco or Time Travel

Would you rather eat a taco, or go back in time as a bug for 5 minutes?

Considerations:

• The taco would be of average quality. It could be hard or soft shell, depending on your preferences. It can have toppings of your choice.
• The time travel could be to any past time, ever.
• As a time traveler, you could get the opportunity to be "a fly on the wall," and could bring your newly acquired knowledge back with you to the future.
• You would return to the present as a human.
• You could die if you select time travel, if you were eaten/swatted as a bug.
• You could die from the taco too (choking, rat poison, etc.)
