0:17.7	If you're a loyal listener, welcome back.
0:19.7	Today you'll learn about a new ink that can 3D print inside your body using sound waves,
0:25.2	why saying no to invitations isn't as bad as you might think, and some new drugs that could
0:30.1	potentially make your dog live longer.
0:32.4	Without further ado, let's satisfy some curiosity.
