Seniors would love to have something meaningful and personalized. You can begin with a list of their hobbies and interests; gardening being the most common. List the things they might need but do not have. Make a list of items that would be of most use to them and select the ones that would matter the most.
Many senior citizens face financial problems. Watching a movie in cinemas, having dinner at a restaurant, beauty salon treatment, etc., might not be affordable for some. So, giving them the gift cards will definitely bring a smile on their face. In short, gift them what they might not have done for years.
Health is of prime concern for the elderly. You can opt for gifts that can help them to manage an emergency particularly if they stay alone. There are many gadgets and services that can help them to monitor their health. A pillbox can be useful for those who find it difficult to remember the medications prescribed.
