Harder to raid the older I get

Hi guys,I’m in a guild that’s currently 7/9H and is going to be pushing mythic soon. I’m one of the two tanks. I find that I’m having trouble with simple mechanics sometimes (tank swapping the correct target on conclave) amongst other things. I’ve been tanking since I was 26–am 40 now. I’m finding it harder to make simple quick decisions on boss fights and it’s really, really depressing.When I first started playing in 05/06’ I was exercising regularly and getting enough sleep—neither of which I’m doing now, so maybe that has more to do with it than my age.Also, I’m still learning these fights. So I need to give myself some credit, BUT...on Mekkatorque I’m really feeling my age.When I get shrunk and need to get in a robot and call out color above other robots it takes me far too long to look at the raid symbol and realize it’s an “x” and then say color above it, quickly. Other guildies just rapid fire the info off, “square you’re green, x you’re blue, skull you’re red,” like super quickly. I literally have to look at the shape, decipher what it is, look at the color above and then say what it is. It takes me like 2-3 seconds to make the mental distinction.Anyway, whole point of this post is to just vent about how getting older sucks, and how my brain can’t keep up with what I want to do.Thanks for listening, friends.
