The problem with many types of modern batteries is that they rely on harsh chemicals to work. Not only can these corrosive liquids damage internal parts over time, but they can also leach into soil and water when disposed of, contaminating them. But researchers from the City University of Hong Kong and Southern University of Science and Technology have developed an alternative, a new kind of eco-friendly battery that runs on a solution similar to the minerals used in tofu brine. The team describes their work in a paper published in the journal Nature Communications. The scientists replaced traditional acids and alkalis with neutral salts of magnesium and calcium to create the electrolyte. These are the same minerals used as brine in tofu production. Keeping this liquid at a neutral pH of 7.0 prevents the type of corrosive reactions that can destroy a battery from the inside out.

Instead of buying fabric softener, which is continual spending and not very good for the environment, let me introduce you to these fabulous little fuckers:

These are wool dryer balls. Instead of fabric softener in your wash cycle, put one or two of these into your dryer. They'll dry your clothes faster, don't come with any harmful or harsh chemicals, and only need to be replaced every few years (or roughly 1,000 loads of laundry)-- which is much longer lasting that fabric softener or drying sheets. Not only are they sustainable and non-toxic, they are safe to use for people with sensitive skin, since there are no chemicals or fragrances that can trigger agitation or allergies.

Control your jealousy even if you're madly in love with your partner and want them all to yourself. If you don't control your emotions, you’ll create constant problems that will make them leave you.

Appreciate the small things even when you don't feel like it. One day you’ll look back at them and realize they were actually big

Do not ignore or take your partner for granted even if you’re passing through not so ‘lovey-dovey’ phases.

Agree on your sexual needs. I'm not saying have sex. You can have 0 sex and be happy together as long as you’re both okay with it.

Master the balance of power. Both of you should have equal control of the relationship. The moment one of you becomes more controlling, you’ll take advantage and abuse each other.

Do not change to the worse for your partner.

Think with your brain and not always with your heart when it comes to relationships, because your emotions can be very intense that they could push your partner away (being TOO affectionate, or being TOO angry, being TOO jealous etc).

Be there for your partner when they need you, even if they claim they don't need you (your job is to feel it without the other person saying it).

Always trust your partner, otherwise problems/jealousy/insecurities will hit you like a truck.

Communicate and solve your problems in a mature way instead of leaving, shouting, fighting and arguing all the time.

Show love and affection. This is crucial specially in long term relationships when you get so used to your partner that you forget that you’re not showing them love the same way you used to in the beginning of the relationship.

Go out of your way for them. They’ll appreciate it and forever be grateful about it.

Open up and let the other partner see you for your true self and nothing less.

Understand your other partner even if you both don't agree on something.

Be positive and happy. Nobody wants a partner that constantly nags, argues for lame reasons.

Be on the same level of maturity. I'm not saying you should be mature to make it work. You can both be immature and work it out. However, a mature person cannot in anyway stay long term with an immature one.

Go on adventures, always discover new things and make your relationship exciting.

Cuddle often.

Most importantly, BE YOURSELF.
