2014Q1
Louis and Maries Crusoe, aged 53 and 51----这个算中年了吧？像这种年纪能算investment horizon长吗？
对比2012Q1和2016Q6
2012Q1: Alonso saves USD 25,000 of his after-tax income every year and plans continue doing so untile retirement.
2016Q6: After paying for living expenses, Paul and Marta Mattison save EUR 100,000 per year, which is added to their joint investment acount in equally monthly installments.
Alonso每年存钱能增加ability to take risk，Mattison夫妇每年存钱能增加ability to take risk吗？原因是？老李上课说后者存款直接进投资账户所以不增加流动性，我不知道他是不是指后者存款不增加ability to take risk。
