The 77-year-old is in his fourth term and hinted earlier this month at the possibility of standing for a fifth in 2015, and these latest comments could be interpreted as an even broader hint that he feels capable of staying on. Current UEFA president Michel Platini has been widely touted as a strong candidate to succeed Blatter in two years' time.
The annual FIFA Congress takes place in Mauritius this week. Delegates will vote this Friday on proposals to limit the age of officials and the number of terms they can serve, and Blatter is concerned that the former change could be open to legal challenge.
He told fifa.com: "I've already said I was against the age limit as I believe it is not a relevant criteria, not everyone is the same at 60, 70, 80, etc.
"It could even be seen as discriminatory. Passion makes the difference. However I am not against a limitation of a number of mandates, this rule applies in many democracies in fact. But then it should apply to everybody."
Earlier this month Blatter was questioned about his future intentions after comments he made at the Asian Football Confederation Congress in Kuala Lumpur.
Talking about the reform process, which he later confirmed would continue until 2015, he said: "This will be the last term of... not of office, the last term of the reform."
