I'm trying to be relaxed about this. Yeah, I'm 50. Just another birthday. I'll take the afternoon off work and lie around the house eating cheese and honey sandwiches, jet planes, and chocolate cake before starting my kale and apples only diet tomorrow. But inside I'm all "how did this happen?!" The lady down the road turned 75 last week, and I realized I'm halfway between my arrival in America 25 years ago, and Betty. This is an odd mixture of "Holy crap the universe is freaky weird," and "well, yes, that is math and that is time, and your point would be?"
In general life is cruising along. I have a nice group of students this year, I'm the lead teacher on social studies, I'm getting back into the garden to get it ready for winter (now that the wasps are calmer), I'm back up to 5.5 miles on my long run. I just have to figure out how to have my nice life, do my job, and have time for other creative projects.
