He shifted the dress so that he could see her leg, and the bruising and swelling were obvious. He touched it gingerly, and he saw Sarah wince. There was no phone in the entryway; Sarah would have had to have pulled herself up the six stairs to the living room to call him; she had neither the sense of balance nor the strength in her other leg to hop. He got out his datacom, and said to it, "Nine-one-one," a term now used as a name in this post-phone-number age.

"Fire, police, or ambulance?" asked the operator.

"Ambulance," Don said. "Please hurry!"

"You’re calling from a mobile device," the operator said, "but we have the GPS coordinates. You’re at—" and she read the address to him. "Correct?"

"Yes, yes."

"What’s happened?"

He gulped for air. "My wife — she’s eighty-seven, and she’s fallen down some stairs."

"I’ve dispatched the ambulance," said the operator. "The data-com you’re calling from is registered to Donald R. Halifax; is that you?"

"Yes."

"Is your wife conscious, Mr. Halifax?"

"Yes. But her leg is broken. I’m sure of it."

"Don’t move her, then. Don’t try to move her."

"I won’t. I haven’t."

"Is the door to your house unlocked?"

He looked up. The door was still wide open. "Yes."

"All right. Don’t leave her."

Don took his wife’s hand. "No, no, I won’t." God, why hadn’t he been here? He looked into her pale blue eyes, which were bloodshot and half-closed. "I won’t leave her. I swear I won’t ever leave her."

He finished with the operator, and put the datacom down on the floor. "I’m sorry," he said to Sarah. "I’m so sorry."

"It’s all right," she said, weakly. "I knew you’d be home soon, although…"

She left the thought unspoken, but doubtless she’d been thinking he should have been home earlier than this.

"I’m sorry," Don said again, his gut clenching. "I’m sorry, I’m sorry, I am so sorry…"

"It’s okay," insisted Sarah, and she managed a small smile. "No permanent damage done, I’m sure. After all, this is the age of miracle and wonder." A song lyric, from their youth. Don recognized it, but shook his head slightly, lost. She gestured with her head at him, and, after a moment, he got it: she was referring to his new, younger form. Now she was holding his hand, comforting him. "It’ll be all right," she said.

"Everything will be fine."

He couldn’t meet her eyes as they waited and waited until, at last, the ambulance’s siren drowned out the thoughts that were torturing him, and everything was bathed in strobing red through the open front door.

Fortunately it was a clean, simple fracture. Orthopedics had come a long way since Don had broken his own leg in 1977, during a high-school football game. The pieces of Sarah’s femur were aligned, some of the excess fluid was drained off, Sarah was given the calcium infusion into her legs that she would have received anyway had the rejuvenation process worked on her, and a small external support was erected around her leg — these days, only dinosaur bones were wrapped in plaster. The doctor said she’d be fine in two months, and, with the support, which had its own little motors, she wouldn’t even need crutches while she healed, although a cane was advisable.

Fortunately, too, their provincial health plan covered all this. Most of the crises in Canadian health care had passed. Yes, there’d been a period when biotechnology had been young during which costs had spiraled out of control, but all technologies come down in price with time, even medical ones. Procedures that cost hundreds of thousands of dollars in Don’s youth now cost a tiny fraction of that. Even sophisticated pharmaceuticals were so inexpensive to develop and produce that governments could give them away in the Third World. Why, someday, even the magic of rejuvenation would be available to all those who wanted it.

Once they got home from the hospital, Don helped Sarah get ready for bed. Within minutes of lying down, she was asleep, helped into the arms of Morpheus, no doubt, by the painkillers the doctor had prescribed.

Don, however, couldn’t sleep. He just lay on his back, staring up in the dark at the ceiling, an occasional band of light caused by a passing car sweeping across it.

He loved Sarah. He’d loved her for almost his entire life. And he never, ever wanted to hurt her. But when she’d needed him, he wasn’t there for her.

He heard a siren in the distance; someone else with their own crisis, just like the one they’d faced today.

No. No, they hadn’t faced it. Sarah had faced it — facedown, on the hard wooden floor, waiting hour after hour for him to return while he fucked a woman less than half — Christ, less than a third! — his age.

He rolled onto his side, his back to the sleeping Sarah, his body tucked into a fetal position, hugging himself. His eyes focused on the softly glowing blue numerals of a digital clock on his night-stand, and he watched the minutes crawl by.

For the first time in years, Sarah was sitting in the La-Z-Boy with it reclined. It was, she said, easier and more comfortable to have her injured leg stretched out.

Despite hardly sleeping at all the previous night, Don was unable to rest; he kept pacing. She had once quipped that they’d both fallen in love with this house at first sight — her because of the fireplace, him because of the long, narrow living room that just cried out for someone to march back and forth in it.

"What are you going to do today?" Sarah asked him. The foot-high digits on the wall monitor showed 9:22 a.m. The windows on either side of the fireplace had polarized, reducing the August sunshine to a tolerable level.

He halted in his pacing for a moment and looked at his wife. "Do?" he said. "I’m going to stay here, look after you."

But she shook her head. "You can’t spend the rest of your life — the rest of my life — as a shut-in. I see how much energy you’ve got. Look at yourself! You can’t sit still."

"Yes, but—"

"But what? I’ll be fine."

"You weren’t fine yesterday," he said, and he resumed walking. "And…"

"And what?" said Sarah.

He said nothing, his back to her. But people who’d been married so long could finish each other’s sentences, even when one of them didn’t want the other to do so.

"And it’s only going to get worse, right?" said Sarah.

Don tilted his head, conceding that she’d guessed correctly. He looked out the brown-tinged window. They’d bought this place in 1988, just after getting married, his parents, and Sarah’s, too, helping with the down payment. Back then, Betty Ann Drive had had a few skinny trees here and there, plus one or two large blue spruces.

Now, those skinny trees, planted for free by the City of North York, a municipality that didn’t even exist anymore, had grown to be tall, luxurious maples and oaks.

He continued walking, now approaching her. "You need me here," he said, "to take care of you."

She looked down at her leg encased in the armature. "I need someone, yes. Maybe Percy—"

"Percy starts grade eight in two weeks," he said. "He’ll be too busy. And Carl and Emily both work during the day. And we can’t afford to hire a home-care worker."

"We could if…" she began, and he mentally finished that sentence: if we sold the house.

He looked out one of the windows again. Yes, this house, small though it was, was bigger than they needed, and had been since Emily had moved out more than twenty years ago. Maybe they should sell it. As was now painfully obvious, Sarah was having real trouble with the stairs. Moving to an apartment would free up money and deal with that problem.
