But how much do you actually know about your own body?

Men and women actually know each other better than at any point in recent history.

"I actually knew probably 95 to 99 percent of the key people."

On the other hand, how much would she actually know?

In fact, she never knew actually when he did go.

And of course he had no idea if she actually knew his name, or not.

We know actually very little about his father and mother.

He would have called her, too, if she had actually known anything.

"We don't actually know their true value because they have never come on the market."

As in, he might actually know what he's talking about.
