Concierge services are very popular these days, especially as the lives of those in business get more and more hectic. A concierge can make life a lot easier for people trying to manage dozens of things at once.
They are also important for senior citizens as they transition to a slower pace of life. As seniors retire, they have more leisure time to enjoy, but these can be restricted by physical limitations. Their needs and required services, then, are going to be different from the ones regular concierges perform.
