Seriously @Tunaormayo74 you should see an independent financial advisor. A good one (like ours) will explore your hopes and dreams for the future and how to spend and invest both short and long term.
You are talking as if you have to choose between some kind of hedonistic lifestyle now and paying (over paying) a mortgage.
Can't you do both?
At it's max when we were paying ours, it was around £800 a month. On a joint 6-figure income, we managed to overpay it and also have holidays (not really expensive ones - as that's not our thing) and pay for 2 kids at uni for 7 years.
We paid it off when we were mid-late 50s. We could have moved upmarket further but a) didn't see anything we liked and b) didn't want another huge mortgage. When we inherited from one side of the family, we passed most of it to the DCs towards buying houses.
TBH it didn't change our lifestyle at all. We saved most of it.
You should also factor in any likely inheritances you may get, if your parents are alive and own property.
As someone else said, you are missing out the part of your life between retiring and dying - and provision for it.
You need to look very carefully at your pension and how they will be valued in 25 years and if they are index linked.
You also might want to look at private medical cover which for me is worth more than a holiday and which we've had for decades both through work and now in retirement.
