Let's imagine 2040 and a future that I would like... I would choose the field of healthcare and longevity.

I would imagine a world where medicine has made huge strides with advanced genetics and regenerative medicine. People would live to a ripe old age in great shape because we would be able to repair damaged tissues, regenerate organs, and prevent serious diseases before they even start. Cancer would no longer be fatal, but a temporary problem that could be easily cured.

Moreover, prevention would be so advanced that people would not have to spend years in poor health. Everyone would have access to personalised medicine - medication, nutrition and exercise would be tailored to their genetic profile and lifestyle.
