What are some advantages and disadvantages?

Depends on the ages.

1) They are likely to die first
2) They can buy you beer
3) they can...

Ok, really, there isn't much of an easy way to answer this. You have given us nothing to work with. As J_9 said, it depends on the ages.

20 and 40

Marrying someone double your age, one disadvantage is that they may die before you do.

Pluses are: older person is more mature, responsible, experienced, confident
Minuses: since he/she is older, this person has already experienced a lot of things without you. And there are things that you want to do with people of your age (go out, dance till the morning, be irresponsible and so on) that an older person would sure find not that exciting anymore

I like the response from marymd. Many 40 year olds really do just want to relax after work, watch TV, go to sleep, and possibly go out once on a weekend. IT DEPENDS! Many 20 year olds want excitement and going out, listen to music jarring to an older person, have a whole bunch of 20 year old friends who don't fit in well with the 40 something friends your mate probably has.
FRIENDS are extremely important to any relationship lasting a long time, so that you don't invest all your energy and emotions in trying to please each other. That only lasts so long.
So YOU tell US how you feel about all that.

Well I had a kid when I was 16 yrs old so I was kind of forced to grow up sooner... I am very mature for my age... ever since I has my son I pretty much gave up hanging out with friends and as I got older it just kind of stuck! I'm a pretty laid back chill person I don't feel the need to go out all the time!we go out to eat and to movies and stuff and that's fine with me... and we have a bar at our house.. so the few nigt that I don't have my son we have a couple drinks together... I was just worried because I might be pregnant!. im not sure how to tell him.. and him being 40 he's only going to live so long to see the baby live...

When he is 70 and maybe has health problems, you will be 50 and possibly his caretaker. And he could develop health problems long before age 70. A twenty-year age difference is huge!

After his divorce, my bil dated a woman a couple of decades younger than he was. He complained that she didn't know anything that interested him -- history, current events, music, and even how to carry on a worthwhile conversation.

In some society, it is more common, as the man will be expected to have a good job. Own a house, have a car and all of his bills paid.

But yes, as you grow older, he may(or may not) have health issues, but it is almost expected that he will die before you. So you will be alone a lot, during your older years.

That was an issue, my wife and I discussed in great detail.
