Hi, Susie!
Nice to hear that your exercise routine with "old school" equipment is working for you!
A stronger body is a happier body.
When I lived in SoCal, I remember a number of people that had the "bed bug" scourge.
They come from outdoors and will creep in through cracks and gaps to the outside (especially near the ground).
Pest exterminators are usually expensive and will often try and talk you into expensive "maintenance plans".
Other than regularly cleaning, vacuuming, and dusting your home, there are few other things you can do.
Here's an excellent do-it-yourself process that you and Mary can do to get rid of the little buggers.
http://www.doyourownpestcontrol.com/bed-bugs.htmOnce you get rid of them, if you use a "bed bug detection system", you can spot them early before they spread.
This website has a link to buy a system for about $8.
Let us know how your "battle of the bed bugs" goes.
