When two hands meet, we pass on something of ourselves. After 【26】______ to Mark Twain, Helen—who was both deaf and blind—commented, "I can feel the twinkle of his eye 【27】______ his handshake." In some indefinable way, Twain had 【28】______ his charm to Keller.

And that's probably been true of the handshake all the 【29】______ back to its earliest days, — 【30】______ no one can tell its actual 【31】______ . A common explanation is that 【32】______ early man encountered a stranger, he 【33】______ out his hand to show he had no weapon. From this, supposedly, 【34】______ the handshake.

Not so, says historian Brian Burke. He believes, the handshake 【35】______ "putting your blood behind your breath." He explains that ancient people 【36】______ the spoken word alone, and they used the handclasp to signify that their 【37】______ was backed up by the 【38】______ of their heart—i, e. , their blood. 【39】______ , the handshake suggested trust.

That 【40】______ of trust has survived to this day. People in business often 【41】______ agreements simply by declaring, "Let's shake 【42】______ it."

Perhaps the most 【43】______ handshake took place on July 17, 1975, during the Apollo-Soyuz get-together in space. After the two crafts came together, American astronaut Thomas Stafford 【44】______ the extended hand of Soviet cosmonaut Alexey Leonov. The 【45】______ to the world was one of friendship and peace.
