I have irregular heartbeats, a heart murmur & high blood pressure. I've been through lots of tests and it was all "nothing to worry about". I hope all is well. Strange to be taking her to the doctor just one week after "meeting" her in person.
Anyway - the high intensity stuff and rushing in is not everybody's cup of tea. It would scare most people off. I'm kind of surprised at your c's take on it. But then - I'm not really that surprised. Some Cs tell you what you want to hear. Or maybe she really "gets it". I'm just wondering why, if she felt that way about MM - she didn't say anything.
But whatever. It doesn't really matter. As long as you're happy. The Museum is awesome and I'm sure you will both have a great time!
