International Master of Memory, Wellon Chou, succeeded in clinching his seventh Singapore memory record by figuring out 22 correct days from just the dates in 5 mins. For example, when asked 29 Jan 1819 (day Raffles landed in Singapore), he calculated it to be a Friday. Chou is the founder and principal trainer at Memory Ark.
