Discriminating people at work based on their age by say, allocating certain work to only people of certain age groups, unfairly presuming capabilities of people based on their age...is ageism.

How then is it legal for people to suggest you must want to (a) get married (b) get a car or home loan (c) have kids in a few years — when you hit a certain age?
My bank's relationship manager recently came home along with a mutual fund guy for upselling some of the bank's products. First question - "Sir, what's your age?" A: 31. His eyes lit up as he launched into his well-rehearsed pitch for planning the future.

I listened, noticed where it was headed, then interrupted, asked him to email me the brochure and GTFO. A colossal waste of time had been averted.
