Question 1

If you could stop time and live forever in good health, what age would you pick? Answers to this question were reported in a USA Today Snapshot. The average ideal age for each age group is listed in the following table; the average ideal age for all adults was found to be 41. Interestingly, those younger than 30 years want to be older, whereas those older than 30 years want to be younger.

Age Group Ideal Age
18 - 24 27
25 -29 31
30 - 39 37
40 - 49 40
50 - 64 44
65 + 59
