Is it wise to invest money into the insurance field?

Yes it wise to invest money in insurance. Insurance mean risk protection. As per risk mitigation all the investment must have a risk protection. 

Eg: There is a 0.0001% probability that there will be a natural calamity in the area where i have invested the capital however if that 0.0001% event trigger than the loss can be upto 100% of the amount invested but if there was a risk cover than the loss will be only upto the insurance cost of investment.

Insurance will always an investment coz it’s a cover for those risk and events which are not in our control and hence its will always an investment. 

Yes, It is wise to invest money into the insurance field

Yes, to some extent. But you got to use your money wisely. Investing in term insurance, some endowment policies along with Mediclaim policies is right idea. 

If you are looking for tax saving then this would be a good option otherwise there are many other options for investment 

No. If purpose of investment is to gain maximum return on investments, better schemes are available as compared to insurance schemes. Insurance products are basically meant for protection/coverage of risks. One should not go for insurance products if priority is for return on investment.

Insurance companies have unique circumstances that make their analysis different from other financial institutions such as banks or lenders. ... As a result, they must invest premiums received conservatively in order to have a ready reserve of liquid assets on hand to pay out those claims.Agents may try to sell you a cash-value policy as a way to invest for retirement. They'll tell you that the investing component serves as "forced savings." (Sure, but retirement plans like 401(k)s force you to save too, once you've taken the initiative to sign up for them.) They'll say the money you have building up in your cash-value policy can grow tax-deferred, but money in IRAs and 401(k)s does too. What they won't tell you is that cash-value insurance is generally a poor investment.

It is a very costly way to invest. There's the cost of the insurance protection itself - which, by the way, is usually more expensive than what you would pay for a regular term insurance policy. There are the marketing and sales commissions. There's also the "surrender charge" that may be levied if you decide to drop your policy within the first 10 years or so. The amount of a surrender charge varies by insurer and type of policy, but it is not uncommon for it to exceed the total amount of your first-year premium.

And, on top of all that, there are annual investment fees. Those are not broken out in all policies, so it's often hard to determine how much you're paying. In policies where they are disclosed (typically variable life or variable universal life policies), however, they can be substantial: 3% or more, year end and year out.

What makes up that 3%? Most of it is the investment management fee, which can run as high as 2% a year. Added to that is an annual fee called the "mortality and expense" charge, which also goes by the name of "M&E." This is essentially a fee thrown in to assure the insurance company a profit, even if all those other fees somehow don't.

The heavy fees involved with cash-value life insurance can really drag down your returns. Especially when you consider that index mutual funds often have annual expenses under 0.5%, and many actively managed mutual funds charge 1% or so. That's a lot less than the 3% or more you'll pay for the investment component on a cash-value policy.

yes it is a good long term investment ,it protect us against un certainty

Investing in a life insurance policy will depend entirely on the financial and personal circumstances of an individual. If a person has liabilities(mortgages etc...) and young children at school, then having a life insuarnce is crucial to protect the assets as well as the family's future. If one does not have any of the above mentioned, then we have to consider their plans. For e'g; are they planning to get married and have children eventually? Are they planning to buy a property? These could trigger the need to invest in a life policy because having it at an earlyy stage means a lower premium for the client. 

It is wise to invest money in Insurance ,  provided you have right guidance for the same. Nowadays there are many fraudelent companies as well as Fraudelent advsiors  who just take and give advice for their own benefits. It is always advised to visit the company website see the schemes do research and development prior before investing in any scheme .

Also there are many schemes in Insurance which give you Tax Benefits which can be beneficial in the long run.

Despite the common misconception, insurers' primary goal isn't to make money from the premiums they collect. If they can, it's a nice bonus, but it's generally not necessary for insurers to be profitable. In fact, many property/casualty insurers regularly operate at an underwriting loss, meaning that they pay out more money in claims than they bring in as premiums.

Instead, insurance companies collect sums of money known as float in advance for claims to be paid later, and invest this money in the in-between time for their own benefit. Essentially, Berkshire's insurance customers are letting them hang on to nearly $100 billion, which Berkshire can invest for the benefit of its shareholders.

Individual policies and claims come and go, but an insurer's float is usually a fairly steady amount over time. As the insurer's business grows, so does its float. In fact, Berkshire's insurance float has grown from just $39 million in 1970 to about $91.6 billion in 2016. Investing the float has been Berkshire's primary mechanism of growth over the years, and is how the company has grown into the massive conglomerate it is today. Buffett refers to the property-casualty insurance business as "the engine that has propelled our expansion since 1967."

It depends in which country you want to invest your money in.

Actully, Insurance is one of the attractive industries for investors, but not in all countries.
