Hey Jack, great yard pictures.  You have a nice place!
It is interesting I have been reading through your diary and it has given me a few insights into my own situation.  I have always thought of you as being in the ideal place, good weight and fit.  Now that I am getting closer to you, not to infer that I am as slim or fit as you, but getting closer.  I can see some interesting parallels.  You are at or near the weight I had been hoping to reach and you still struggle with a bit of belly fat and wanting to do more.  Kind of the same as I am feeling now, except that you are slimmer and fitter than I.  Anyway I appreciate being able to follow your role model.
Your 100 pushups a day is very impressive to me.  I just started trying pushups about a month ago, could not do a single one.  So I started with doing them on my knees, and it was even hard to do one that way.  Now I am up to 30 of the on knee pushups and doing a few regular ones.  Your 100 a day is a good inspiration to me to keep after it!  Have also been doing the occasional crunch, at your suggestion.
