[00:00.00]2 The early bird catches the worm…
[00:04.80]The early bird may catch the worm-but people
[00:07.60]who lie around in bed in the morning
[00:10.06]and work into the evening are more intelligent,
[00:13.28]according to Richard Roberts
[00:14.49]of the University of Sydney.
[00:16.67]The scientists asked 400 volunteers
[00:19.24]to fill in questionnaires to work out
[00:21.33]if they considered themselves
[00:23.61]early-rising"morning types"
[00:25.94]or late-working"evening types".
[00:28.66]Each was then subjected to mental agility¹
[00:31.99]and memory tests.
[00:33.97]The researchers discovered
[00:34.98]that the "evening types" had significantly
[00:37.11]better mental speed and memory.
[00:39.79]"The results indicate that,contrary to
[00:41.82]conventional folk wisdom,evening types are
[00:44.49]more likely to have higher intelligence scores,
[00:48.02]Roberts told Sunday Telegraph.
[00:50.43]He also suggested that the link between
[00:52.38]intelligence and working late may be a
[00:54.78]hang-over from prehistoric² times,when those who
[00:57.99]were still alert after dark would be more
[01:00.84]likely to survive attacks by
[01:02.98]nocturnal predators³.
