Someone asked about pensions. I have a pension from my years of inpt full time hospital work - >20 yrs.
Hospitals have notoriously horrid pensions - always have even before the the change from defined benefit to defined contribution. I have both.
I also have 401K's & 403B's (non-profit equivs to 401Ks).
I plugged the numbers - for my own situation, it did not make financial sense to go beyond 20 years for employment. That also corresponded with my desire to leave that employment, so it all worked out.
I have a significant number of years into another retirement plan - fortunately, the vesting years are small.
For the individual who said some of us work part-time due to boredom, its not usually boredom - its not having to put up with "stuff" that comes from full time work.
Finally, for the pharmacy student who didn't think those of us who are older are as knowlegable on pharmaceutical care - that may not always be the case, altho I'm sure you can find examples which are true. However, with experience comes wisdom & knowing how much & when to give out information, what is significant & what is not & how important it is to demonstrate our knowledge.
Some of the most knowledgable pharmacists I've ever worked with are older than me - I still learn from them.
The OPs question was demand. The number of >65 yo pharmacists won't significantly affect demand - that will be the marketplace.
