Avoid sugar, simple carbs, milk, meat. Embrace natural and raw food. Enjoy spices, ghee, butter. Take adequate water.
Avoid chronic cardio. Long walks and yoga is more than enough. Occasionally lift heavy stuff such as your own body.
Avoid investment advisors with vested interests. That is 99.9% of the folks out there.
Invest in a diversified set of direct plan mutual funds. Or get a SEBI RIA advisor with no 'allied arms' seeking commissions.
