" Cleaning out the lint trap of the dryer . I watched a neighbor ’s house burn down because of this . "

Sometimes, for whatever reasons, we think of something as not that serious and that we can hold off on dealing with it. For example: Someone putting off going to the dentist because of toothache from a cavity, and when they do end up going they have to get a root canal because they didn’t go in sooner.

And recently, Reddit user300teethgirltouched upon this topic when theyasked: “What do people heavily underestimate the seriousness of?”

1.“High blood pressure. It’s the silent killer for a reason.”

2.“Breaking up with a friend. This whole ‘clean out your social life, everyone is toxic’ thing these days has gone way too far. You should be willing to put up with people’s foibles. Friendships are not limited in number the way monogamous partners are, so you shouldn’t be dumping them for every little thing. It’s brutally painful on the dump-ee. Save friendbreakupsforreallyserious problems.”

3.“Sleep deprivation.”

4.“Water damage. I work in construction and the number one cause of claims is water damage. Roof leaks, wall leaks, concrete damage, you name it. Water is the worst enemy of building.”

5.“Not having a will.”

6.“The content you post to the internet.”

7.“Infections. Especially urinary tract infections. They can kill you.”

8.“The69% reductionofanimalpopulations since 1970.”

9.“Loneliness and how it impacts pretty much everything in your life.”

10.“Cross-contamination in food prep. I’ve run into SO many people who just don’t understand why it’s an issue. And it shocks me every time.”

11.“Driving. People recklessly throw those multi-ton machines around on the roads like it’s no big deal.”

12.“Cleaning out the lint trap of the dryer. I watched a neighbor’s house burn down because of this.”

13.“Water/the ocean, those that grow up around it understand. Those that don’t just assume they can swim. Another dangerous assumption is that because there are life guards/supervision, it is safe. You can drown in a few seconds. Also, there isn’t many risks that you just jump into. People understand not to jump/walk into fire or jump/walk off a cliff but will be willing to jump/walk into deep water.”

14.“Vitamin B12 deficiency.”

15.“Slipping and falling. They get included in compilations of ‘funny’ videos, I see it and I cringe. Having slipped on ice and broken my wrist a few years ago, it was a very painful and scary experience — not funny in the slightest.”

16.“Maintaining your health throughout your life.”

17.“Skin cancer. Melanoma, in particular. Sunscreen can go a long way in preventing it, but people routinely go out in the sun without protection. It’s also important to have your skin checked regularly with a melanoma, especially if you have any suspicious moles.”

18.And lastly: “Addiction to social media.”
