1. Beyond life
One of the biggest unanswered questions about life is – what happens after it ends?
We all have to face death at some point, and for thousands of years humans have been pondering on whether death really is the end, with our concepts of an afterlife varying greatly.

5. A taboo subject
For many of us, the topic of death and what comes after is still considered strictly off-limits in conversation.
A survey of more than 2,000 people, commissioned by the Dying Matters Coalition, found:
- A third of people in the UK think about death and dying at least once a week.
- The majority of those don't make a will, secure life insurance or register for organ donation.
- More than half of Britons in relationships do not know their partner's 'end-of-life' wishes.
- The most common age at which people would like to die is between 81 to 90 years old.
- 79% of those surveyed also said quality of life was more important than longevity.
