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 22 year-old 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 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 fast-acting 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 in Asia sometime early next year.

The unpunctual man， on the other hand， never does what he has to do at the proper time. He is always in a hurry and in the end loses both time and his good name. A lost thing may be found again， but lost time can never be regained. Time is more valuable than material things. In fact， time is life itself. The unpunctual man is for ever wasting and mismanaging his most valuable asset as well as others. The unpunctual person is always complaining that he finds no time to answer letters， or return calls or keep appointments promptly. But the man who really has a great deal to do is very careful of his time and seldom complains of want of it. He knows that he cannot get through huge amount of work unless he faithfully keeps every piece of work when it has to be attended to. Failure to be punctual in keeping ones appointments is a sign of disrespect towards others. If a person is invited to dinner and arrives later than the appointed time， he keeps all the other guests waiting for him. Usually this will be regarded as a great disrespect to the host and all other guests present.
