現今有許多人離鄉去工作或求學，這些外來人口常因諸多不便無法自行烹飪而選擇外食。與此同時，許多長輩因為子女離家而形成空巢期。這些銀髮族雖然家中有廚房、廚具且善於烹飪，但因為家中人口有限，原本烹煮的飯菜量因無法一餐吃完又捨不得浪費，而常需要重複加熱食用，長期下來不僅不健康，也會造成身體的負擔。因此，本研究設計了“Share” App，希望透過App 讓外食族嚐到美味的家常菜，同時解決空巢期菜餚過剩的困擾。除此之外，本研究更希望透過這個共享平台的建置，讓供餐的長輩得以提高主觀幸福感，進而產生正向的老化。

Many people today leave their hometowns for schools or for work. These people are away from their homes so they often choose to eat in the restaurants or take-out food because it is inconvenient for them to cook in their rentals. At the same time, many elders become empty nesters because their children left home. These silver-haired people often have kitchens, cookware and other cooking related tools and they are also good cook since they have a lot of experience in cooking. However, because they become empty nesters, the family size shrinks. When they cook, they often have leftovers. Reheating leftovers is not only making the food less tasteful but also destroying the nutrients in the food. Based on these facts, the researchers have designed the “Share” App. This App is to address the need of traveling students and/or workers for tasty home-cook food and to solve the excess home-cook food issues for silver-haired population. In addition, the solution provided by this study may improve the silver haired elders’ well-being and lead to their positive aging.
