Imagine this: You're bleeding. Nothing seems to make it stop. Then you apply a gel to your wound, and the blood stops coming out within seconds. You're healed in minutes. This is the VetiGel, created by Joe Landolina—a 22­year­old who invented the product many years ago.

Landolina is now the founder and CEO of Suneris, a company that produces the gel. Suneris announced last week that it would begin to ship VetiGel to vets later this summer. Humans won't be far behind.

When injected into a wound site,  the gel can form a clot within 12 seconds and heal the wound within minutes. Once it hits the damaged tissue, whether it's open skin or a soft organ-livers, kidneys-the gel instantly forms a structure. "What that means, on the one hand, is that the gel will make a structure that holds the wound together, " Landolina says.

As fast­acting as VetiGel is,  its inventor may be faster. Landolina invented an early version of the gel out of his grandfather's lab. He was still in high school.  Over the next four and a half years, Landolina turned the prototype into a business. The first product costs  $150. Landolina says Suneris has its sights set on US first, followed by a release in Europe and Asia sometime early next year.

A few years down the line,  Landolina says, the goal will be to expand out of vet offices to help treat members of our own species. He forecasts receiving FDA approval within the year for testing on human wounds. If all goes according to plan, VetiGel will first help military personnel and EMTs treat injuries. Then it will enter operating rooms and, finally, individual homes.

Landolina says Suneris has yet to observe any negative side effects of VetiGel. The company holds weekly meetings with vets to ensure the product meets their needs.

Last week after my motorcycle crashed on the freeway, I wanted only two simple things from technology: to call 911 and to tell loved ones where I could be found. When she opened Google Maps, she could see precisely where I was.

For years, tech companies have offered different ways for people to tell one another where they are. If used carelessly, location tracking may hurt your privacy. But used thoughtfully, it can be a powerful and efficient communication tool.

•When you make plans to meet friends somewhere like a movie theater, get into the habit of sharing your location for a short duration, like an hour. This way you can skip saying things like "I'm on my way" or "I'm running a few minutes behind" because people can simply follow you on the map.

Location sharing can be useful for being considerate of your partner's time and space. For example, I  am less likely to text my partner when I see she is at the office or driving on a freeway, but I will text when I see she is at the grocery store to ask her to pick something up.

•Next time you plan an event at a large outdoor space, do your friends a favor: Wandering around aimlessly in a crowded open space can be annoying.

A.Here are my suggestions for the best time to use it.

B.For safety reasons, avoid sharing your location publicly.

C.Use an app to share your current location so they can find you.

D.Consider sharing your location occasionally with your partner.

E.There are many ways for third parties to find out where we are.

F.Yet location tracking has caused controversy for the last decade.

G.Before calling 911, I texted my partner who was already tracking my location with an app.
