• What number is your water bottle?

  Did you guys hear about the numbering system for plastic bottles?
  Check the bottom of your plastic bottles for a triangle symbol with a number inside... If it has the numbers 3, 6, or 7, don't drink from it!
  
  I got this email below recently and apparently, re-using plastic bottles by refilling them is NOT a good idea. (You'd think it's a great way to save money and help the environment, but instead it could be toxic for your body). In Hong Kong, tap water isn't clean enough to drink so I filter/boil water at home to drink, and I always bottle up water in reuseable plastic bottles to bring out with me on a hot summer day or to my yoga classes to keep from dehydrating.
  
  Scary enough, I found that these plastic bottles that I use are made with some of the most toxic plastics (number 7 on the numbering system). I immediately threw these away just to be safe. I guess if I can help it, I'll just avoid the "toxic" numbers and look for the safer numbered bottles. It seems like many bottled waters use #1 plastics, which seem fine to drink from once, but not recommended for repeated use.
  
  Here's a video which Matt Lauer talks with Dr. Leo Trasande of the Mount Sinai School of Medicine about just how (un)safe are plastic bottles:

  Did you ever drink from a plastic bottle and see a triangle symbol on the bottom with a number inside?
  
  
  Do you know what the number stands for?
  Did you guess that it's just for recycling?    
  Then you are WRONG !!!!!!
  THE NUMBER TELLS YOU  THE CHEMICAL MAKE UP OF THE PLASTIC.....
  
  (1)    Polyethylene terephalate (PET)
  (2)    High density polyethylene (HDPE)
  (3)    Unplasticised polyvinyl chloride (UPVC) or Plasticised polyvinyl chloride (PPVC)
  (4)    Low density polyethylene LDPE
  (5)    Polypropylene (PP)
  (6)    Polystyrene (PS) or Expandable polystyrene (EPS)
  (7)    Other, including nylon and acrylic
  What you aren't told is that many of the plastics used are toxic and the chemicals used to create a plastic can leach out of the plastic and into the food / drink.
  The WORST ONES are Nos: 3, 6, and 7 !!!
  DO NOT USE THOSE NUMBERS if stated at the bottom of the bottle) !
  
  (Errr, the reuseable bottle that I have is a number 7... )
