T-Rex: Let's say the average person can expect to live for 81 years. That's a little over 2.5 billion seconds.
T-Rex: Honestly, I - I kinda thought it'd be more.

T-Rex: 2.5 billion is really not that much!

T-Rex: I thought I'd compare the seconds in a life to the molecules in a glass of water, but even a gram of water has over ten sextillion molecules in it! Even if I measure my life in NANOSECONDS I'm still not on par with a gram of boring ol' WATER.
Dromiceiomimus: Molecules are super tiny, T-Rex! You should measure yourself in bigger units.
T-Rex: Like... cubic millimeters?

Utahraptor: That'd give you 2500 litres. That's a lot!
T-Rex: Dude, that's just a GIANT BATHTUB.

T-Rex: I want to visualize my lifespan as something impressive!
Utahraptor: Okay: 2.5 billion kilometers is enough to make a one-way trip to Saturn and get most of the way back before dying, OR to travel part of the way to Uranus, but again, dying well before you arrive.

Narrator: LATER:
T-Rex: Dear audio diary! Today I learned why we measure lifetimes in years and not in "failed trips to Uranus where only corpses show up at the end".
T-Rex: It's, um - for the reasons you'd expect, basically.
