Well, this is a first. I'm posting on an "exercise" thread as someone who will actually exercise.
DH and I joined a local gym this weekend. DH is in fabulous shape, but hasn't had a workout buddy ever since he cancelled his trainer when the prices rose. So DH has been wanting to work out, and I'm not capable of being a spotter for him but the local gym has excellent machines for DH, and machines, classes, ellipticals for me. I have a date to meet DH there at 5, right after I drop DD off for a class in the same shopping center. So no skipping! 
I am IN NO WAY an exerciser, but am looking forward to the end results. Post-40, I've seen my body doing shape-shifting that's really scary. I'm tall enough to still look OK, but between you & me
I'm several pounds heavier than I was when I married, & would like to get back there! Also, my mom is in pretty flabby, weak shape from a lifetime of being sedentary; I live in my two-story dream home and want to be able to chase my grandkids up the stairs someday, so it's time to get moving.
Valerie, congrats on your great bike ride! I envy your stamina; maybe I'll get there sometime.

As you cook, you enjoy omniscience about food that no amount of label reading can match. Having retaken control of the meal from the food scientists, you know exactly what is in it. (Unless you start w/cream of mushroom soup, in which case all bets are off.) To reclaim control over one's food, to take it back from industry & science, is no small thing; indeed, in our time, cooking from scratch qualifies as subversive. ~~ Michael Pollan
