He's pretty cool but this joke was not funny in the moment. I've been obsessing over having a brain tumor for a few weeks now. When I told him that it was a worry a few minutes later I asked him a question and he said he's between a "brain tumor and a pinched nerve" my heart fr dropped it and I freaked out bit. He immediately said he was joking and he asked if I had anxiety. He then went on to teach me a good technique for anxiety which was awesome and then proceeded to readjust me. 

I didn't not find this funny at the time but I'm now able to laugh about it. Anyways the technique is put your hand on your chest and one on your Timmy and just take breaths and hold it for a second then release. I've been up for 24 hours at this point due to my anxiety and I can not wait to sleep adjusted.
