I'm 39 and already worried sick about retirement. I didn't start consistently paying into a pension till I was about 30 and I'm doing my best to make up for lost years but I think I'll be very lucky if I can afford to retire at all let alone before I'm 75.
Our team's PA is in her late 50s and will probably be retiring in a few years. She's down to 4 days a week and there's nothing particularly wrong with her bar the usual niggles that people get as they get older, but she says she's tired and some days it's really a struggle, and (not being unkind here) some days she really does look worn out. She also looks after an elderly relative and this causes her lots of stress. She would love to retire now, not from laziness but because she's just so tired.
We don't do manual jobs, we sit at desks for most of the day, but even so I can't imagine how tired I'd be if I was still doing this at 70. What about the people who have only ever done manual jobs? Surely a 70 year old can't be expected to still be putting in 40 hours a week on a building site, but what's the alternative for them? Retail type jobs are already competitive with teenagers/students and mums of young children wanting jobs that fit around school hours all applying for the same jobs while half of the high street seems to be shutting down.
I don't want to get old at all. I've seen too much of it lately. Family and friends who have been fit and healthy all their lives ending up having to go into residential care because they have dementia; people downsizing and getting rid of 90% of their treasured possessions so they can go and live in a tiny retirement flat; people being plagued with pains and illnesses of every kind and people requiring care to be able to wash/dress/go to the toilet. There are very few people I know aged say 80+ whose lifestyle I would be happy to have if I live that long. I think I'd prefer to enjoy the money I earn while I can, knowing I'd be taking myself off to a nice clinic, Soylent Green style, once I turned 75 and so wouldn't need to fund a miserable retirement.
