  • PSA whitening toothpastes are just normal toothpastes with added abrasives. So they temporary whiten your teeth because you’ve removed the outer most enamel which gives your teeth its hardness. At the mere cost of tooth sensitivity and future staining, the deeper dentine layer is much softer and porous which is easily damaged by acidic foods but also more easily stained due to the porosity. So congratulations your teeth are now more stained.

    You know it when you go to work and it doesn’t feel like work. It doesn’t feel like an absolute drag to get out of bed.

    I’m an HVAC engineer. I love my job, to me it’s like spending all day solving logic puzzles or a detective mystery. I found I was pretty good at it about 6 months into the job, when I figured out a problem the senior techs couldn’t. I enjoy being out and about instead of chained to a desk.

    A job/career doesn’t have to be a passion. Just something you don’t dread everyday. My passion is in sports but somehow engineering was something I was good at, it felt satisfying fixing things. I’d never make my passion my job cause I know it would completely ruin it for me.
