A) Older people can't hide their age when they apply for a job.
B) Workers become less productive as they get older and have less energy, so it is harder for them to get promotions.

D) Older workers have to use their medical benefits more often, so companies charge them higher premiums for insurance.
E) The jobs of older workers can be in jeopardy when companies are downsizing.
