Krypto is like the financial system, but different.

It doesn't care where you come from, what you look like, your credit score,

or your outrageous food delivery habits.

crypto is finance for everyone everywhere all the time.

Krakhan, see what crypto can be.

Don't invest unless you're prepared to lose all the money you invest.

This is a high-risk investment, and you should not expect to be protected if something goes wrong. There's an anthropologist named Dr Helen Fisher. She studies love. She's been at it for more than 40 years.

And she says love is very simple. She said

timing is important, proximity is important, mystery is important.

She tries to understand what it means to be in love,

asking people things like,

what percentage of the day and night do you think about this person?

Would you die for this person?

And then, along with her colleagues Art Aaron and Lucy Brown,

she's put these people into an fMRI machine and showed them a picture of the person they love and watch their brain.

She said that love is not an emotion, it's a drive,

and one of the most powerful brain systems on Earth

for both joy and sorrow.

In one experiment, they looked at the brain activity of 17 people who were in love and felt that they were loved in return.

And then they looked at the brains of 15 people who had just been broken up with, but said they were still in love with the person.

I've been watching a TED Talk given by a woman named Dr Helen Fisher.
