Your friends proposal should be based on what you are financially capable of as well as what kind of coverage that is important to you.

If you think you can't afford it in the first place, you should have voice it out that you need something that is within your budget.

Get your friend to properly advise you.

I don't t know about your background but if you're young, you can plan to get yourself covered for medical expenses first, should you want to add on other riders such as death, disability and critical illness then investment link is ideal. As long as whatever plan that you have in mind, you have something to fall back on in case of an emergency.

But don't overspend too much on insurance when you're young.

Lifebalance has given you very good advice. However it still comes back to your own budget and needs.

1) It is true
2) Insurance is necessary if you currently do not have any. Start with a medical coverage and add life coverage and critical illness.

Best,

Friend, I applaud you for sticking to your friend.
I also really respect you that you trust your friend and support him/her to grow together with you for many years to come.
For you, he is the kind of friend you want to keep for life.
For him/her, I believe you are that friend too.

I want to appeal to you to go one step further to trust his/her advise and proposal to you.
There are many agents on this forum like me who wish to seek for business.
I believe your friend, an insurance agent just like me, really appreciates your support for him/her.
At the same time, just like how you are learning new things everyday in your career, he/she is too.

Now I grew up in an agency office. My whole family business is insurance.
If I told you I have learned everything there is about insurance, I am lying to you.
I am still learning new things everyday just because I am doing my job diligently everyday.

With that said, I believe as a form of respect to your friend, maybe you can suggest to meet with his agency leader to get to know his/her agency better, or maybe you can ask him these questions that you are asking here.
Otherwise, with all the different agents here slapping your friend's proposal to you left right and center, I feel that it is very unfair to your friend simply because your friend is the one that knows you best! 

All the agents here can only go as far as to hint you "there is a cheaper option with me" or in other words "I'm cheap" to lure you over. Simply because we don't know you.
We don't know what you want, we don't know what you need, we don't know where you want to go, we don't know what is the difference between a 100k and a million life sum assured is to you, but we know everybody is trying to get something extra, we know everybody is just as Harry Markowitz described.
To all the agents here, you're just a username "violetlace". We don't even know your name.

If my two cents is of any worth, I encourage you to engage your friend telling him/her "hey, got some time for me? I have a lot of questions that I would like to ask you before committing."
If you're my friend and you call me with that sentence, i tell you... my feeling betul-betul  !!
I would feel respected.
