To live long you must

I think that the most important thing to make our life longer is to be healthy and live in country where is clean air.If you do exercises every morning you will be healthy.Than it's to have money but not very much,eat but not too much to be fat and eat vegetables and fruits,sleep and be happy with friends.i do all to  live long:I have fiends in school and in our street,I eat healthy thing,do exercises.But I don't live in a country where is clean air :(
