In this new video from Virus Watch, I tackle the thorny question of whether viruses are alive.

I always worry this is a pseudoquestion. It seems like it should have an answer, but it doesn’t because the world is messy and humans like neat categories.
I understand what you mean. Humans make up their own definitions, what do they really mean? But because I’m very involved with viruses, I had to give my own opinion here.
