Warping?

I broke out my 12-string today. The only acoustic guitar I currently have. I had a six string too but I loaned it to the singer in my band years ago and I don’t know if I’ll ever see it again.

I’m worried about my 12-string. Is the neck starting to warp a little? I hope not.

I was thinking of making any new songs I work on this month be acoustic guitar focused, but after playing for a few minutes this morning… this thing is hard to play. I might be changing my mind a little.

Addendum: For future reference, this is a Takamine F-400S and based on the serial number on the neck block inside the guitar it was built in March of 1978.
