Many craftsmen in Denmark are working contracts where they get paid more the faster they finish the job, and nobody wants a 70 year old dragging down their hourly wage just because they can't keep up, so the 70 year old will just have to "keep up", either making mistakes along the way, or wearing out their already worn out bodies some more.
There are options for "early" retirement at 70, provided you've spent 46 years employed. That means you started working at 24 at the very latest, and was not unemployed for longer periods.
Saving up for your own retirement is also hard with low to medium income wages in a country where you pay 40-50% income tax, 25% sales tax and retirement funds are taxed at deposit (meaning capital gains will be lower).
