Dragonheart here! Merlin has been posting so far, so now it's my turn.
No, I'm not a grumpy old fart. Yes, I do save my energy most of the time, but I can still play and run around like a crazy cat when I'm in the mood. Yes, I have a grade 2 heart murmur, and I'm equivocal for hypertrophic cardiomyopathy, but fortunately I don't need to be on medicine for it. I also have asthma, and I take a puffer every morning. I've only needed to use my rescue inhaler a couple of times over the past year, since starting the preventative puffer in the morning. So I think I'm entitled to be a "lump" most of the time.
Here I'm enjoying the heating pad (nice and comfy under it) since my crazy siblings are running around like mad cats, so I have the heatie pad all to myself!
