Concession fares for senior citizens

I made some research about the concession fares for senior citizens.

Here is a brief summary:
* available to citizens and permanent residents, aged 60 and above
* available during off-peak periods (see below for peak hours)
* bus rides: 65 cents per trip (air-con), 60 cents (non-air con)
* train ride: $0.66 to $1.52, depending on distance (but lower than standard fare)

Peak hours:
SMRT: up to 9 am and between 4.30 pm to 7 pm on weekdays
SBS: up to 9 am on weekdays
