Developing universal manual sign languages for the deaf

International deaf signing should be standardized and taught in further education, at infant school level or earlier, for the following universal reasons: (a) global interchange could take place with only one universal language to learn; (b) crowd control, in dangerous situations, would be easier to manage; (c) persons born deaf or suffering later hearing loss would understand and be better understood in the population; (d) classrooms may be quieter and yet afford sharing of information and ideas; and (e) most basic essential skills would be attained faster because of this extra mnemonic.
