Exactly.

Hehe, we are old.

And it didn't feel that good walking to lunch. Damn.

I'm sure I had a problem like this long before I was as old as I am now... but I don't remember why it eventually disappeared.

This Gubb Vader guy didn´t attack me until I was about 10 years older than you are at the moment. Had problems off and for maybe 10 years after that but not so much now - probably due to better (more strength) and/or less competitively geared training speeds. Intervals are very rare these days.
