Dear Dr. Jim
I'm writing this in hopes that you can help me out.
My feet are killing me! Seems none of the shoes I ever can buy really fit me. At least that is what my son tells me.
What can I do with this if the shoes don't seem to be helping my feet?

Dear Ms. Tenderfoot
Your shoe story is great! My uncle used to say that 'if the shoe didn't fit then don't wear it.' That is the gist of your problem, I like that you've figured that much out! Beware of your son's not-so-helpful advice.
My foot doctor has me wear athletic shoes all the time with an arch support, the green generic kind that sporting goods stores sell. Mine are NIKE runing shoes. My church and dress shoes are a pair of black walking shoes also fitted with arch supports.
Without the arch supports my feet get to hurting pretty fast. You might like to try that with the arch supports.
Hope this helps, Dr. Jim

Dear Dr. Jim
I was in the Office Outpost office supply store yesterday and overheard the sales clerk talking with a customer.
He stated that the battery in the lap top computer the man was thinking of buying should be disconnected when charged and the computer was on AC power from the plug.
My husband says that is all malarkey as the new NiCad technology used in the rechargeable batteries can be left plugged in all the time.
Who is correct?

Dear Scared To Not Pull
You husband is almost correct this time. There was a time when lap tops used NiCad rechargeable batteries. They developed a memory as to where 'total discharge' was. Invariably this was wherever the batteries were charged from the last time.
Modern laptop batteries are Lithium Ion (LiIon) and will not be significantly overcharged and will not develop a memory if allowed to charge fully after battery operation.
They are very much subject to overcharging, but the modern lap top has electronic circuitry to carefully keep the batteries at optimum performance and prevent overcharging. LiIon's are not subject to memory characteristics to a great extent. [Reference link]
Periodically this circuitry needs to be recalibrated. Check your computer manual for the procedure on this or call the appropriate tech support line for your lap top. The above reference gives generic directions for the recalibrating effort.
You might do that store a favor by telling them and e-mailing them with this. And a copy of this Ask Dr. Jim (blog) session.
I hope this helped,
Dr. Jim
Some other battery tidbits:
°°°°Each computer is engineered for a certain battery. You should not place just any old battery that will fit into your computer. Buy what the lap top manufacturer requires.
°°°°Be sure to buy lithium ion batteries for your digital camera, most are AA cells. You should also get a charger made especially for the LiIon batteries.
°°°°[Here is a link for you Toyota Prious owners about overcharging your battery. It won't happen.]
