Proper dental hygiene is something that one should make a habit from a young age. By the time one realizes its value, like I did, it might already be too late.
Ditto with sleep hygiene. Those two are habits that I think should be learned and reinforced from a young age.
I only wish I can actually go ahead and buy one; good pillows as well.
But then again, I’m just in a really shitty financial situation. Maybe when things turn around for me, I can invest on those.
