At some points, it was even days. The fact he's got both Stardust and Surfer with him at the same time is a bad thing. The last time I saw that, he was weakened from the Annihilation war and feeding more frequently because of it.

I'm hoping it's just something that happened again, but if not, he might be from the time period he was at his most hungry.

And there are two reasons life still exists in my universe. One is that the universe is an awfully big place, with an awful lot of systems and planets. The other is the Surfer. He's been one of his major heralds for ages and he has a lot of respect for life. When he's not fighting against Stardust he tends to lead Galactus to as many worlds without sentient life as possible.

He doesn't even want to be Galactus' herald but he's taken it on time and again just to make sure that whoever was his herald was leading him away from eating sentient beings. By doing that, he's probably saved billions and billions of people.
