My age was 47 years and I'm retired from army on 31 Aug 20 Can I invest in senior citizen investment scheme

 Why not !!

It is very good decision because savings never bluff with you. it will always support you like a family member financially or mentally.

  you'r bright future and many dreams of your's depends on your savings and systematic investment is more important in this journey. many of peoples invest in some viral tips like someone said now a days sbi shares or mutual funds growing then you should invest in that Stop!!! it is really take you for loss because no one can decide what will happen in next 2 min. 

So please don't depends on tips they are just assuming but you need to do analysis what is financial. how's the income, balance sheet, cash flow. it is basic analysis you should understand first before investing somewhere. 

everything should be in your mind.

1. strategy.
2. analysis.
3. benefits.
4. risk.
5. return of your investment.

 Of these things will clear then there is no chances to stuck.

Investment Areas -

1. Stock market.
2. Mutual funds.
3. Cryptocurrency.
4. Forex trading.
5. Real estate.

I gonna suggest you first 2 options Stock Market, Mutual Funds. because these are most returnable things of your investment in very less time as you can spend time on it. or Forex trading, crypto is also second option because it will take time but it is also indoor work.

it will increase your health and wealth as usual.
