The smaller breeds of rabbit, like the Holland Lop, live on average 7-10 years with proper care. However, it is not unheard of to see rabbits living into their teens. Rabbits usually live longer if they are spayed or neutered, which is always recommended.
Think about where you think you'll be in the next 10 years. If the answer is singing and dancing on Broadway, do you think your rabbit get in the way of that? Or if you want to get a rabbit for your child, but he/she will be going off to college in 7 years, do you want to be stuck at home looking after the rabbit?
If you're going downhill financially, and you know you won't have enough money for a rabbit 10 years from now, don't buy one.
If you are newly married and want to start a family, don't buy a rabbit if you think it might get in the way of you raising your first child or bringing home the baby. Children and rabbits can grow up together, and become fast friends, but ask yourself if you're prepared to work towards that. It won't happen overnight. The rabbit may become jealous of the newcomer at first.
If you are prepared to power through everything life has to offer with your rabbit, then welcome to the world of rabbits!
