This is sort of a shower thought because this morning I was using some shaving cream and I thought, if it turns out in 5 years this was giving me cancer, I wouldn't be surprised.
Comes out a goo, ejected from a can with force, immediately becomes a foam?
Do you have anything you use that you think might be too good to be true?
A bit of advice from some dental organizations and my family member who is a dentist, you really shouldn't use the same toothbrush twice a day. The toothbrush should be left to completely dry out before reusing and that takes longer than 16 hours in most climates.
