Let us define what you meant when you retire. 65 years old is the retirement age to everyone who is employed. There is no age limitation continuing one's business in SFI. This means that you can still continue your business after retiring from the employment.
You are not an employee in SFI, but entrepreneur. Your business depends on your decision whether to continue or stop and loss the interest of continuing our businesses with SFI.
Since you are an entrepreneur, there is no such thing as retirement since you can recruit a family member as your downline, pass on your SFI business to a family member anytime you wish or heirs through your last will when you die.
I advise you to view this so you can ensure yourself that your business continues to grow and provide income for your beneficiaries: https://www.sfimg.com/ReviewSIM/SFIComparisonChart.pdf
