People are often asked are they glass half empty or glass half full sort of people.

And you may have wondered why some people just seem to have a more positive outlook on life,

why some people always just seem to be happier than others.

Take my little brother, Sunil, for instance.

He's about 10 years younger than me.

He's in his mid-40s, and for as long as I can remember he's been this sort of happy-go-lucky

sort of guy. Even at a young age he just always seemed to have a sunny disposition, and frankly

he's still kind of liked that today.

Now the thing is I consider myself to be a pretty happy person,

but compared to him and our family,

I was always more the kermogen.

And it kind of made me wonder, was he born that way? I mean we have the

same parents, we grew up pretty much the same and yet this particular thing, how happy we are by default, seems to be different.

Some people are just happier than others. They don't have to work at it, right? They just are.

That social psychologist Sonia Lubimerski. She's been studying happiness for over 35 years.

She's a professor of psychology at the University of California Riverside,

where her research and her lab focus on understanding various aspects of happiness.

She's also written a few books on the topic.

But what really interests me is the professor's hands-on data-driven research on happiness.

For years now, she's been doing studies to see what exactly makes people happier.

She calls them happiness interventions.

So today I'm chasing life, a question I've often wondered about.
