Bacteria stay alive because some of them are in "hibernated" form (forgot the term) and are resistant to very high/low temps, drought, etc
Hot water doesn't increase the rate of degradation in PET. Degradation only occurs at a meaningful rate at a temperature hotter than any water you'd put in there.
Other things in the environment can degrade PET, like UV light, but if it's indoors, chances are it's not going to degrade from the office lamps.
There ARE traces of heavy metal in your plastic water bottle. Zinc, Titanium, Antimony, and some other metals are used to make PET. They exist in very, very small amounts and are trapped by the plastic, so you don't need to worry about them leeching out.
There's only one thing you'd need to worry about leeching out of the bottle. It's a gas at room temperature and it's a degradation product that forms during the bottle making. It can diffuse into your water and make it taste "fruity". It's naturally occurring in fruits and vegetables. Water bottles typically have very strict requirements for this degradation product, so chances are you'll never even notice it.
The biggest thing to worry about is bacteria and mold. PET bottles are your friend, don't be afraid of them. Continue to drink bottled water by the truckload, because it helps keep me employed.
