My swelling is gone

After giving up meat and diary, I did not notice any changes.  And then I looked down after a few days AFTER HAVING SIX INTERNATIONAL flights and my knees and ankles have absolutely no swelling.

My ankles and my knees are completely normal.  Or...as normal as can be.  I have no swelling anywhere.  I am so interested in other changes that could be happening in my body.  How do you know?  Well, I just had my bloods done a few weeks ago so I would like to have them done in a few more months just to see what happens.  How else can I measure?  My weight.
How else???
