I would guess it had a rotten spot that didn't change the appearance very much. I was eating one of my watermelons this summer and kept thinking it didn't taste right. Finally figured out it had a small exterior defect where an insect had eaten on the skin of the small fruit and was now rotting on the inside. Just check the others closely first to see if they have a soft spot on the outside. If the fruit is sound it can't hurt you. It probably won't hurt you if you ate a half rotted one. The Fruitnut

Are you under some new stress? I have found I am always hungry if I'm bored in the evening or under stress. If I have quilt or craft projects in the evening, I don't eat too much. Also, if I take my dog for a long walk just before dark, I don't eat as much and also I sleep better. If these ideas don't apply to you, I suggest that you see your doctor and ask about those supplements. Good luck.

Solved, my parents are apparently not very observant. She decided to change the batteries in the downstairs even though the display was showing, flipped the breaker and after that it worked. Changing the batteries didn't work for the upstairs though. The repairman came out and Replaced smart valve gas control, blower motor and capacitor on second floor. Luckily, they have a service contract. She thinks that one of them has probably not worked for a while, but since the other one did they didn't notice it until the second one went out which is when they noticed neither one worked. No telling which one went first. I suppose it fits in the category of coincidence, or oblivious......mystery solved.

Thanks for all your quick replies. GC has a mold remediation company coming out tomorrow. I agree that there had to be something during the construction process. Especially since the mold is only in the pipes and trusses. There are 5 other units in the building. I'm going to ask them if they have had similar issues. The units were closed within 5 months of with ours being the last. One last question... if they come in and spray some chemical on the mold, what's to say it won't come right back? None if the units have insulation on the pipes, even those built years ago so I don't think GC will just insulate ours. If that's the answer, is it expensive?
