"Once I get set up, I'll probably try to open my own business." "And spend your weekends on Luna." Craig half rose from his cot, jarred into anger. But the old spaceman turned, smiling wryly. "Don't get hot, kid. I guess I spent too long in Zone V." He paused to examine his wrinkled hands. They were indelibly marked with lever callouses. "You get to thinking anyone who stays closer'n eighty light years from Terra is a land-lubber." Craig relaxed, realizing he had acted childishly. "Used to think the same. Then I took the exam and got this job." "Whereabouts?" "Los Angeles." The old man looked up at Craig. "You don't know much about Terra, do you, son?" "Not much." "Yeah. Well, I hope you ain't disappointed." "My father was born there, but I never saw it. Never hit the Solar System, matter of fact. Never saw much of anything close up. I stood it a long time, old man, this hitting atmospheres all over the Universe." But the spaceman seemed to have lost interest. He was unpacking some personal belongings from a kit. "What are you doing in Grav 1?" Craig asked. The old man's face clouded for an instant. "In the old days, they used to say us old-timers acted like clocks. They used to say we just ran down. Now they got some fancy psychology name for it." Craig regretted his question. He would have muttered some word of apology, but the old man continued. "Maybe you've read some of the old sea stories, or more'n likely had 'em read to you. Sailors could go to sea until they just sort of dried up. The sea tanned their skins and stiffened their bones, but it never stiffened their hearts. When they got old, it just pulled them in. "But space is different. Space is raw and new. It tugs at your guts. It sends the blood rushing through your veins. It's like loving. You don't become a part of space the way you do the old sea, though. It leaves you strictly alone. Except that it sucks you dry, takes all the soup out of you, leaves you brittle and old--old as a dehydrated piece of split leather. "Then one day it shoots a spurt of blood around in one of your old veins. Something gives. Space is through with you then. And if you can stand this whirligig conditioning, you're through with space." * * * * * "_You can't figure it. Some of 'em urp all over and turn six shades of green._" "_You got to watch the ones that don't._" "_Yeah, you got to watch the ones that don't. Especially the old ones._" "_He's old. You think it was his heart?_" "_Who knows?_" "_They'll dump him, won't they?_" "_After a tracer is sent through. But it won't do any good._" "_He probably outlived everybody that ever knew him._" "_Wouldn't be surprised. Here, grab his leg._" * * * * *
