Singer Dolly Parton was born on this day in 1946. For most who've been working 9 to 5, it's nothing to sing about. Even computers get tired. Is your PC wearing out? Getting old? Ready for replacement? What do you do with an old PC anyway? The Environmental Protection Agency says not to toss it in the trash. It's loaded with lead, mercury and other toxins that can reach from landfills into our soil and drinking water. Experts advise you to get your money's worth instead by donating it to a reputable charitable organization which, in turn, will give you a receipt that can be used for a year-end tax deduction. Also many schools lack funds for new computers. Giving them yours can help (it's a tax-deductible donation, too). This year, 55 million PCs will become obsolete. That's a lot of trash. Or, far better, a lot of help. Your choice. And that's the On The House tip for today.
