I've had my snake plant for about two years now and it's honestly the easiest thing in my collection

I've had my snake plant for about two years now and it's honestly the easiest thing in my collection. I barely water it and it just keeps growing new leaves. My question though: is it normal for the older leaves at the base to look a bit yellow? I'm wondering if I should remove them or if that's just part of the plant doing its thing. I'm still learning to read what plants are telling me, but so far this one seems pretty forgiving.
