In the modern society, technology has become pivotal in our every day lives. One way technology can now help us survive and thrive would be using e-medical services. For example, some high-tech countries now allow online consultation with doctors for diagnosis, skipping the long lines in clinics and can be potentially life-saving.

Another way technology has helped us would be using self-serving kiosks and home delivery services for our daily groceries. Working adults may be exhausted to get groceries so with the ease of online grocery shopping, they have the ease of saving time to spend time with loved ones. Self-serving kiosks have also helped workers by cutting the queues and reducing fatigue.
