Beside from the voting systems, there are
three main ways to cast a vote. By person (going to a poll station), by proxy
(giving permission for someone to vote on your behalf) and by post.
Many requirements in the UK voting system have been amended over the
years, from women being granted the vote in 1918, to the legal age being
lowered from 21 to 18 in 1969.
Across the world the legal age varies between 16 and 21 but for most is
18. For some time in the UK there has been question whether the vote should be
lowered to 16 and for an age group who are already allowed to work, gamble in
the lottery, join the army and get taxed for working, personally, voting should
be in that list.
