Quick question about blinds...

[imashyboi]

I just wanted to ask this to players cause it's been bugging me. I notice in higher limits, games like 15/30 and 30/60, where the blinds are 15/10 and 30/15, people tend to come in with more garbage. Even if the pot is raised I'll see some loose callers calling with almost anything in these spots. I've seen people calling with 65o, I'm sure that's a mistake overall but how about a 65s?

I think I'm playing too tight in the blinds so I am trying to losen up. I'm just curious what hands should be played in these spots.
