I have 3BB Fibre out in the jungle 35 kms from City centre. 1000/500 Gb/s. Get that most of the time as if it is ever needed.

Retirement extension. Either 800k in the bank 5 months of the year and 400k the other 7 months OR 65k a month from abroad (via Wise?) and you can spend every last satang of it. Bank statements and book copies required ONCE A YEAR. Done.
