You engineering guys (and gals?) ROCK!--Here's another for you re:  Electric toothbrushes?

Just stick it on the charger.  How long do you think it is going to last anyway?  The batteries will keep it going fine like that for 5 years.  \n\nWhat does it matter if it lasts a week or 10 mins when you only brush your teeth for 2 min?

Electric shavers tend to be for people who really don't need to shave very much or have very soft beards.  I find them to be worthless.  I'd much rather have some good after shave or cologne.

Educated about them? I invented some of them! :)

Brush your teeth and floss. Duh...

Electric trolling motors have come a long way.  With the new style batteries, you can fish for most of a day without loosing power.  I'm a big fan and think they are worth every penny (I used to run a trolling plate, this is MUCH better!).

You are on the right track. It relies on inductive charging:\n<quote>\nIf you own an electric toothbrush, there's a good chance that it has a completely sealed toothbrush unit. The toothbrush rests on the charger without any metal contacts to connect the toothbrush to the base. This has the great advantage of allowing the toothbrush to be completely sealed so that water cannot enter through exposed contacts. It also avoids any problems with water getting into the contacts and shorting out the charger.\n\nThis sort of sealed arrangement is called inductive charging. Essentially, the toothbrush and the base form a two-part transformer, with the base having one part of the transformer and the toothbrush having the other. When you slide the toothbrush onto the base, the complete transformer is created and charge can flow.\n\nThe base contains one of the coils and the metal bar. The toothbrush contains the second coil. When you drop the toothbrush onto the base, you create the complete transformer!\n</quote>

I'm a sucker for new ideas!  My most recent purchase was the knife block that allow you to stick your utensils anywhere-it looks like bristles on a broom when you take it out. (Sorry, I can't think of what the actual name is for it)  And, I used to own a Chia Taz!

http://news.bbc.co.uk/2/hi/health/3679313.stm\n\nNew teeth 'could soon be grown'\n \nLiving teeth are better for gums than false ones \nTechnology to grow replacement teeth could mean the end of dentures. \nScientists at King's College London have been awarded £500,000 to help them develop human teeth from stem cells. \n\nThe company Odontis, set up by the college, hopes to develop its research for tests on humans within two years after successful research on mice. \n\nStem cells, the so-called master cells, would be programmed to develop into teeth and then transplanted into the patient's jaw where the gap is. \n\nIt is thought it would then take two months for the tooth to fully develop. \n\nHealthy gums \n\nBut it could be five years before the technology is widely available to the general public. \n\nOn average Britons aged over 50 lose around 12 teeth out of 32. \n\nProfessor Paul Sharpe is the genetic research scientist behind the technique and head of division of Craniofacial Biology and Biomaterials at the Dental Institute at King's College. \n\nHe said: "A key advantage of our technology is that a living tooth can preserve the health of the surrounding tissues much better than artificial prosthesis. \n\n"Teeth are living, and they are able to respond to a person's bite. \n\n"They move and in doing so they maintain the health of the surrounding gums and teeth." \n\nThe cost should not be more than the price of synthetic implants of between £1,500 - £2,000. \n\nHis project has been awarded £300,000 from the Wellcome Trust, £100,000 from the National Endowment for Science, Technology and the Arts (Nesta) and £100,000 from a business sponsor. \n\nA spokesman for the British Dental Association (BDA) said: "The BDA welcomes projects like Odontis and looks forward to seeing further progress in this field." \n\nhttp://edition.cnn.com/2004/WORLD/europe/05/03/teeth.replace/\n\nhttp://forums.stangnet.com/archive/index.php/t-517536.html

A grill for your teeth?  please explain!\nand if you mean metal teeth things, DONT GET THEM!!  They're sooo ugly!

your fingers, electric toothbrush, hair brush handle, detachable shower head, water faucet, etc. Use your imagination!

Always get a second opinion. They are out to make money. I saw a dentist and he said I had 5 cavaties!!! I went to another and had only one small cavity. They will rip you off!!! Also, who in the heck needs a $100 toothbrush? Go buy a sonic care one at Target or Wal-Mart. They are the best. Take action and let them know that you are going elsewhere.

Molly has a good point.\n\nWhich one do you really like?\nIf you like them both, then you are as same as me.\n\nLet's see...\nElectric engineering. Sounds cool, do you think not?\nYou get to make cool electrical stuffs such as fridges, irons, air conditioners, lamps and others which are beneficial to humans, am I right?\n\nSocial Science?\nIt is more general and less complex than Pure Science I presume.\nHowever, it is still cool and beneficial.\n\nIn order to learn Electric Engineering, you must study Additional Maths, Chemistry, Physics and two more other things, right?\n\nAdditional Maths, Chemistry, and Physics?\nWOW!\nAren't they super-cool?\n\nHow about Social Science's subjects?\nChemistry, Biology, Additional Maths and EST?\nThe fun is getting better!\n\nWhich one should you choose?\nBoth of them sound interesting to me.\nHow about take them both?\nJust kidding.\nTo me, they look the same and related.\nWhich means it is good if you master them both.\n\nI assume I am not making sense here, right?\n\nIt all depends on your enthusiasm rather your ability.\nChoose what you really want, not choose what you think is easier.\n\nAlthough Electric Engineering might sound easier for you because of the absence of Biology which you must remember scientific names for the subjects in it.\nBut if you really like Biology, then remembering scientific names is a snap for you.\n\nRemember,\n"Enthusiasm tops over ability".\n\n\nAh, yes. Future jobs.\nFor EE, you can apply as an Electric Engineer in companies like Phillips, Sony, Braun and others.\nFor SS, you can work as an anthropologist or physiologist or others.\n\n\nDo consider rechecks, I am typing without references so mistakes must occur.\nGood luck for you!

electric trimmers are great, they sell tiny ones for the oh so   important areas...... but why is this question under the mental health headline?

mechanical or electronic?
