Beer keg to heart anatomy and physiology lesson

Borrowed from a CPR instructors group on Google Groups that I belong to:

If I want a beer and I pump the keg 5 times and pour 1 lousy beer, the pressure drops back down (G1992)

If you and I team up and pump the keg 15 times and pour 2 OK beers, pressure still drops (G2000)

If we team up and pump the keg 30 times we get 2 really good beers (G2005)

If we pump the keg 50 or 100 times it kills us before we get a beer (50:1 & 100:1 studies)

This ends our beer keg to heart anatomy and physiology lesson for today.

Interesting analogy on the progression of compressions to ventilation ratios.

Customer service

A few weeks ago I was told in an email that I didn't know the difference between customer service provided by a service provider and customer service provided by a store clerk.  It wasn't suggested in a nice manner so it's something I've been mulling off and on for a few weeks.  I knew I would blog about it, but wanted to make sure I wasn't reacting to the tone of the email. I guess for me there really isn't a difference. As a service provider (my courses) I do my best to meet the needs of my clients.  I can't tell you how good it makes me feel to receive positive reviews on the evaluation forms I use at the end of my classes.  I also greatly appreciate anyone who provides a good service for me.  It doesn't matter to me if you are a clerk in a store, the person bagging my groceries, the customer service associate on the phone or someone I've hired to perform a job or task.  I'm quick to thank them for a good job.  If I get one of those stor...

Quotes

Every morning I post a quote on Facebook.  Occasionally I'll post a second, but usually just the one. A while back someone asked me why I do it.  That was all they would see from me for an entire day sometimes.  They told me they're on Facebook to see what we're all up to and the quote didn't tell them much about me. A few others have liked, loved, and/or commented on the quotes.  Apparently they enjoy them. I read a quote every morning and I share it.  They are random, not on any specific topic or theme.  As I read and post them I spend a few minutes thinking about them and how they impact me or what is going on with or around me.  It's like a thoughtful meditation that helps me to mentally set up the day ahead of me. I hope you enjoy them as much as I do.

Summer work

Image
The past 3 years I've worked at summer camps.  I'd volunteered for 3-4 years before that at Cub Scout Day Camp for a week - it's only 1 week.  But the past 3 years I was paid staff at Camp Seawood. I enjoy working at camp.  I'm outside all day without a cell phone.  It's almost Nirvana - almost because I'm surrounded by kids.  But for the most part they're all awesome. This summer I decided to not work at camp.  I did end up volunteering at Cub Scout day camp the  last week in  June.  This is Micaela's last summer before going to NHIA.  I wanted to have time to do fun things with my kids. But I usually teach fewer classes in the summer because fewer people sign up.  It's hot, people are on vacation, it's normally a slower time of the year.  I still need bring in some income to pay for the summer adventures. I was fortunate to be able to book enough private on-site classes that covered the income I would have made at sum...
