San Francisco (I) -- Swimming Pool (II)

I am in San Francisco for a meeting. I arrive early to set everything up and discover that the room is occupied until 5 PM so I decide to go for a swim in the local pool. Not a long walk from here, just a lots of hills. This is San Francisco after all.
I have my first surprise arriving there: it's free. Apparently it's free on Tuesdays. Or maybe it's free only today. In any case, I'm in without having paid a dime and the pool is OK, if not incredibly cold. The water is a least 5 degrees colder than my local pool. I can swim for 20 minutes and still feel the water fresh on my body. As I am nearing my usual kilometer swim, I am seized by crippling cramps. I decide to stop and head back in. The place is quite dirty and not really welcoming so I get dressed to go back to my hotel for a hot shower. A woman enters the dressing room. She was the one sharing the lane with me. She smiles and asks me how I am and I realize she saw me struggling out of the pool with my cramps. I explains that my right calf was killing me. She listens and then with a smile tells me "too bad I didn't know it was cramps. The remedy for cramps is very simple." She points to somewhere between her mouth and her nose and she continues "all you have to do is push somewhere there". "You have to find the correct point though. But it's somewhere here". She is pushing here and there, tracking an invisible "mustache" with her finger while explaining the principle of this point and its importance in acupuncture.
I love California.
